- Bring down to 7: 4 goes into it 1 time; 7 − 4 = 3
- Bring down to 35: 4 goes into it 8 times; 35 − 32 = 3
How to use it
Enter the dividend and a whole-number divisor to see the long division written out.
The answer is exact: whole numbers of any size up to 30 digits are handled without rounding, and Show the working lists every step.
Key facts
dividend = divisor × quotient + remainder
The steps
Divide: how many times does the divisor go into the first digits? Multiply and write the product underneath. Subtract. Bring down the next digit and repeat until there are no digits left. What remains is the remainder.
Questions
What is 75 divided by 4?
18 remainder 3, or 18 3/4, or 18.75.
How do I divide by a decimal?
Multiply both numbers by 10 (or 100) until the divisor is whole: 5 ÷ 0.5 is the same as 50 ÷ 5 = 10.
