Quotient and Remainder Calculator
Compute integer quotient and remainder with the division identity
Calculate Reset
Division Algorithm
a = bq + r
The quotient q counts full divisor groups. The remainder r is the leftover amount after those groups are removed.
⚠
Note: This calculator uses integer division. The divisor cannot be zero, and the remainder is reported using the mathematical nonnegative convention.
How Quotient and Remainder Work
Integer division splits a number into a whole-number quotient and a leftover remainder. Together they reconstruct the original dividend.
Division Identity
The identity a = bq + r verifies the quotient and remainder.
Whole Groups
The quotient q tells how many complete groups of size b fit into a.
Leftover Part
The remainder r is smaller than the absolute value of the divisor.
Check Step
Substitute q and r back into a = bq + r to confirm the result.
Example: 47 divided by 6 gives q = 7 and r = 5, because 47 = 6 x 7 + 5.

Frequently Asked Questions
What are quotient and remainder?▼
The quotient is how many whole times the divisor fits into the dividend. The remainder is what is left over.
What is the division algorithm?▼
The division algorithm writes a dividend as a = bq + r, where q is the quotient and r is the remainder.
Can this calculator handle negative integers?▼
Yes. It returns a mathematical nonnegative remainder for integer division.
