About the Long Division Calculator

Long division finds how many times one number (the divisor) fits into another (the dividend), giving a whole-number quotient with a leftover remainder, as well as the exact decimal result.

Formula: Quotient = trunc(Dividend ÷ Divisor) · Remainder = Dividend − (Quotient × Divisor)

This is the standard technique for dividing multi-digit numbers by hand and underlies modulo arithmetic used throughout mathematics and computing.
