Quotient Calculator
Enter a dividend and a divisor to get the integer quotient, the remainder, the exact decimal, and the mixed-number form. The show-your-work panel walks through every step of the long division. Negative numbers and decimal inputs are both supported.
What is a quotient?
When you divide one number by another, the quotient is the integer (whole-number) part of the result. For example, 17 divided by 5 gives a quotient of 3, because 5 fits into 17 exactly 3 whole times. The 2 that is left over is the remainder. Together, quotient and remainder let you reconstruct the original dividend: quotient x divisor + remainder = dividend (3 x 5 + 2 = 17). The word "quotient" comes from the Latin "quotiens," meaning "how many times." The decimal form of 17/5 is 3.4, and the mixed-number form is 3 2/5, which expresses the same value as a whole part plus a proper fraction in lowest terms.
How to use this calculator
Type the dividend (the number being divided) and the divisor (the number you are dividing by) into the two fields. The quotient, remainder, decimal result, and mixed-number form all update as you type. For negative numbers, the "remainder convention" selector matters: truncation (the C and Java standard) produces a remainder whose sign matches the dividend, while floored division (the Python standard) produces a remainder whose sign matches the divisor. For positive numbers the two conventions are identical. The show-your-work panel traces every arithmetic step, including the verification check (q x b + r = a).
The long division algorithm
Long division works digit by digit from left to right. For 487 divided by 32: first consider 4, which is smaller than 32, so bring in the next digit to get 48. 32 fits into 48 once (1 x 32 = 32), write 1 above the line and subtract: 48 - 32 = 16. Bring down the next digit (7) to get 167. 32 fits into 167 five times (5 x 32 = 160), write 5 above the line and subtract: 167 - 160 = 7. The quotient is 15 and the remainder is 7, so 487 = 15 x 32 + 7. To continue to decimals, append a zero to the remainder (70), and 32 fits into 70 twice (2 x 32 = 64), giving the next decimal digit 2, and so on.
Negative numbers and remainder conventions
When either the dividend or the divisor is negative, there are two mathematically valid ways to define the quotient and remainder. Truncation toward zero (used in C, Java, JavaScript, and most calculators) gives: -7 / 2 = -3 remainder -1. Floored division (used in Python and most mathematics texts) gives: -7 / 2 = -4 remainder 1. Both satisfy q x b + r = a, they just distribute the fractional part differently. The floored convention is often preferred in modular arithmetic because the remainder is always non-negative when the divisor is positive. Use the selector at the top to switch between the two and compare.

Frequently asked questions
What is the difference between quotient and remainder?
The quotient is the integer result of a division - how many whole times one number fits into another. The remainder is the amount left over after removing those whole groups. For 19 divided by 4: the quotient is 4 (because 4 x 4 = 16 fits inside 19), and the remainder is 3 (because 19 - 16 = 3). The decimal result 4.75 combines them: 4 whole parts plus 3/4.
How do I find the quotient without a calculator?
Use long division. Write the dividend under a division bracket and the divisor to its left. Work through the digits of the dividend from left to right: estimate how many times the divisor fits into the current working number, write that digit of the quotient above the bracket, multiply to get the product, subtract from the working number, and bring down the next digit. Repeat until you have processed all digits. The number left at the end is the remainder.
Can the quotient be negative?
Yes. If exactly one of the dividend or divisor is negative, the quotient is negative. If both are negative, the quotient is positive (a negative divided by a negative is positive). The remainder sign depends on the convention: truncation keeps the remainder sign matching the dividend, while floored division keeps it matching the divisor.
What does it mean if the remainder is zero?
A remainder of zero means the divisor divides the dividend exactly, with nothing left over. In other words, the dividend is a multiple of the divisor, and the decimal result is a whole number. For example, 24 / 6 = 4 remainder 0, because 6 x 4 = 24 exactly.
How is the quotient different from the decimal result?
The quotient is the integer part only - it drops any fractional portion. The decimal result keeps the full precision: 7 / 2 has a quotient of 3 (dropping the 0.5) but a decimal result of 3.5. The mixed number 3 1/2 expresses the same full value as a whole number plus a proper fraction. All three representations are shown by this calculator.
What is a mixed number and how is it calculated?
A mixed number is a compact way to write an improper fraction by separating the integer part from the fractional remainder. For 17/5: the integer part is 3 (because 3 x 5 = 15), and the fraction part is 2/5 (because 17 - 15 = 2 remains), giving the mixed number 3 2/5. The fraction is always reduced to lowest terms by dividing both numerator and denominator by their greatest common divisor (GCD).
