Remainder Formula
The remainder is calculated using the formula: Remainder = Dividend - (Divisor × Quotient) where the quotient is the integer result of division. In programming, this is often expressed using the modulo operator (%): dividend % divisor.
How to Use This Calculator
1. Enter the dividend (number to divide) in the first field
2. Input the divisor (number to divide by) in the second field
3. Click "Calculate Remainder" to get instant results
4. Use "Clear All" to reset the calculator
