Modulo Calculator

Calculate the remainder of division between two numbers quickly and accurately. Free and online tool for mathematical operations, programming, and everyday calculations. Ideal for developers, students, and professionals who need to calculate the modulo (remainder) of a division.

What is Modulo?

The remainder of division (also called modulo) is the value left after dividing one number by another. For example, when we divide 17 by 5, we get 3 as the quotient and 2 as the remainder. In programming, the % (modulo) operator is widely used for cyclic calculations, validations, and algorithms.
