Frequently asked questions
What is the remainder in long division?
The remainder is what remains after taking the largest whole-number multiple of the divisor that does not exceed the dividend in magnitude under the chosen convention.
Can I divide by zero?
No. Division by zero is undefined, so enter a nonzero divisor.
