Perform division with step-by-step long division work. Enter dividend and divisor to get quotient, remainder, decimal result, and fraction form instantly.

Key Takeaway

Use the free Division Calculator to perform division with step-by-step long division work. find quotient, remainder, decimal result, and fraction form for any dividend and divisor. Get instant results with step-by-step explanations.

How to Use the Division Calculator

  1. Enter the dividend (the number being divided).
  2. Enter the divisor (the number you are dividing by).
  3. Review the quotient, remainder, decimal result, and fraction form.
  4. Follow the long division steps showing each subtraction and bring-down.

The Formula

Division with remainder: Dividend = Divisor × Quotient + Remainder. The remainder is always non-negative and less than the absolute value of the divisor.

Variable Definitions

  • a: The dividend (the number being divided)
  • b: The divisor (the number dividing the dividend)
  • q: The quotient (the result of the division)
  • r: The remainder (what is left over after division)

Dividing 73 by 8

Perform 73 ÷ 8 using long division.

  1. Step 1: How many times does 8 go into 73? 8 × 9 = 72, which is the closest without exceeding.
  2. Step 2: Quotient so far: 9. Multiply: 9 × 8 = 72.
  3. Step 3: Subtract: 73 - 72 = 1. The remainder is 1.
  4. Step 4: Express results: 73 ÷ 8 = 9 remainder 1, or 9.125 in decimal, or 9 1/8 as a mixed number.
  5. Step 5: Verify: 8 × 9 + 1 = 72 + 1 = 73. ✓

Frequently Asked Questions

What is the formula for division?

The fundamental relationship is: Dividend = Divisor × Quotient + Remainder. For example, 23 ÷ 5 = 4 remainder 3, because 23 = 5 × 4 + 3.

How do I do long division step by step?

1) Divide the first digit(s) of the dividend by the divisor. 2) Write the quotient digit above. 3) Multiply and subtract. 4) Bring down the next digit. 5) Repeat until all digits are processed.

What happens when the divisor is larger than the dividend?

The quotient is 0 and the remainder equals the dividend. For example, 5 ÷ 8 = 0 remainder 5, or 0.625 in decimal.

Can I divide by zero?

No. Division by zero is undefined in mathematics. The calculator will show an error if you try to enter 0 as the divisor.

How do I convert a remainder to a decimal?

After finding the remainder, continue the division by adding a decimal point and zeros. Divide the remainder (times 10) by the divisor repeatedly to get more decimal places.

What is the difference between integer and decimal division?

Integer division returns only the whole-number quotient (discarding the remainder). Decimal division returns the exact result with decimals. For example, 7÷2 = 3 (integer) vs 3.5 (decimal).

How do I express the result as a fraction?

The result as a fraction is (Divisor × Quotient + Remainder) / Divisor. As a mixed number: Quotient and Remainder/Divisor. For 73÷8: the mixed number is 9 1/8.

What is the order of operations for division?

Division and multiplication have the same precedence and are evaluated left to right. In expressions like 12÷3×2, divide first (12÷3=4) then multiply (4×2=8).
