How to use: Perform long division with quotient and remainder. Enter Dividend (number being divided) and Divisor (number dividing by). Results show: Quotient (whole number result) and Remainder (leftover amount). Formula: Dividend = (Divisor × Quotient) + Remainder. Examples: 17 ÷ 5 = Quotient 3, Remainder 2 (17 = 5×3 + 2). 100 ÷ 7 = Quotient 14, Remainder 2. Decimal conversion: 17÷5 = 3.4 = 3 + (2/5). Applications: splitting items evenly (divide 17 items among 5 people = 3 each with 2 left), time calculations (125 minutes = 2 hours 5 minutes), measurement conversions, modular arithmetic. Essential for elementary math and practical division problems.
