What is the Long Division Calculator?
Long division is a method of dividing two numbers to find the quotient (how many times one number fits into another) and the remainder (what's left over). This calculator automates the process and provides the exact decimal equivalent.
How it works
Enter a dividend (the number being divided) and a divisor (the number you're dividing by). The calculator computes the quotient as a whole number, calculates the remainder, and determines the exact decimal result. It also verifies the answer using the formula: divisor × quotient + remainder = dividend.
dividend ÷ divisor = quotient R remainder, where dividend = (divisor × quotient) + remainder
When dividing, the quotient is the whole number of times the divisor fits into the dividend. The remainder is what's left. The decimal result shows the complete division as a decimal number. The verification ensures divisor × quotient + remainder always equals the original dividend.

Notes
1234 ÷ 56
22 R 2 (22.036)
56 fits into 1234 exactly 22 times with 2 left over.
100 ÷ 7
14 R 2 (14.286)
7 goes into 100 fourteen times with a remainder of 2.
999 ÷ 9
111 R 0 (111)
When remainder is zero, the division is exact.
How to use the Long Division Calculator
Write the dividend on the left and the divisor on the right, separated by a division bracket.
Determine how many times the divisor fits into the first digits of the dividend.
Write the quotient above the division bracket.
Multiply the quotient by the divisor and subtract from the dividend section.
Bring down the next digit and repeat until all digits are processed.
The final remainder completes the long division.
Benefits
Understand division structure by seeing quotient and remainder separately.
Quickly verify your manual long division calculations.
Convert division problems to exact decimals for precise calculations.
Check homework or test answers instantly.

Tips & common mistakes
Common mistakes
Forgetting that remainder must always be smaller than the divisor.
Confusing dividend and divisor (dividend is divided, divisor divides).
Assuming an exact decimal when there's actually a repeating decimal.
Not checking that divisor × quotient + remainder = dividend.
Tips
The remainder is always less than the divisor—if not, increase the quotient.
Use the decimal result to see the full division answer as a single number.
The verification formula is your quick check: does divisor × Q + R = dividend?
If remainder is zero, the division is 'exact' with no leftover amount.
Frequently asked questions
What's the difference between quotient and remainder?
The quotient is how many whole times the divisor fits into the dividend. The remainder is what's left over after dividing. For example, 17 ÷ 5 = 3 R 2: quotient is 3, remainder is 2.
Why do I need both quotient and decimal?
Quotient and remainder show the answer as a whole number plus a remainder (useful for real-world scenarios like distributing items). The decimal shows the exact division as a single number, useful for calculations and measurements.
Can the remainder be bigger than the divisor?
No. If the remainder is bigger than or equal to the divisor, the quotient is too small. The remainder must always be smaller than the divisor.
What does 'R' mean in quotient and remainder format?
'R' stands for 'Remainder.' So '22 R 2' means 'quotient of 22 with a remainder of 2.'
What if I divide by zero?
Division by zero is undefined and impossible in mathematics. The calculator prevents this and alerts you if you try.
Are decimal results always exact?
For whole number inputs, the decimal shown is exact to 10 decimal places. Some divisions have repeating decimals beyond that precision.
