Comprehensive Calculator Guide
This calculator divides two numbers by long division step by step, as taught at school: divide, multiply, subtract, bring down. It gives the quotient, the remainder and the decimal result, including repeating decimals such as 176.(285714). 1234 ÷ 7 = 176 remainder 2.
The steps
Take enough digits from the left to cover the divisor, divide, multiply, subtract and bring down the next digit; repeat. Check: dividend = divisor × quotient + remainder. Continue past the point with zeros for decimals; a repeating remainder gives a repeating decimal.
How to Use
- Enter the dividend.
- Enter the divisor.
- Press “Divide” to see the quotient, remainder, decimal and steps.
Formula Used
Dividend = divisor × quotient + remainder, remainder < divisor
Practical Examples
- Example 1: 1234 ÷ 7
- 176 r 2; 176.(285714).
- Example 2: 9876 ÷ 12
- 823 exactly.
- Example 3: 100 ÷ 8
- 12 r 4, or 12.5.
Important Tips
- Estimate first.
- Write a zero when the part is too small.
- Check by multiplying back.
Common Mistakes to Avoid
- Missing a zero in the quotient.
- A remainder bigger than the divisor.
- Bringing down two digits at once.
