Modulo Calculator

Calculate the modulo (remainder) of integer division a mod b, with quotient breakdown.

Formula & Calculation Rule

How It Is Calculated

a mod b = r where a = q × b + r, 0 <= r < |b|

Divide a by b to get integer quotient q; remainder r = a - (q × b).

Step-by-Step Example

29 mod 5

129 ÷ 5 = 5 with remainder 4

25 × 5 + 4 = 29

Result: 4 (Quotient: 5)
