What Is A Remainder?

The remainder is the amount left over after division. It is the value that makes the identity dividend = divisor x quotient + remainder true.

How To Find The Remainder

  1. Divide the dividend by the divisor.
  2. Find the integer quotient.
  3. Multiply the quotient by the divisor.
  4. Subtract that product from the dividend.
remainder = dividend - divisor x quotient

Worked Example

For 17 divided by 5, the quotient is 3 and the remainder is 2.

17 = (5 x 3) + 2

Frequently Asked Questions

Can the remainder be negative?

For this tool, the quotient is truncated toward zero, so the remainder follows the division identity used here.

What if the divisor is zero?

The calculator rejects the input because division by zero is undefined.

Can I use decimals?

Yes. The calculator accepts decimal values and returns a decimal remainder.

Is the remainder always smaller than the divisor?

Not in every sign case when negative values are involved, because truncation is used here.
