To divide numbers, the most common method is long division, which breaks the division problem into multiple easier steps. Here's a concise guide on how to divide using long division:
- Write the dividend (the number to be divided) and the divisor (the number you are dividing by).
- Take the first digit of the dividend from the left.
- Check if this digit is greater than or equal to the divisor. If yes, divide this digit by the divisor, and write the quotient on top.
- Multiply the quotient by the divisor, write the result below the first digit of the dividend, and subtract.
- Bring down the next digit of the dividend.
- Repeat the process until all digits have been brought down.
- The number written on top is the quotient (result), and any leftover number is the remainder.
Example: Divide 735 by 9
- 7 is less than 9, so take 73.
- 9 × 8 = 72, subtract 73 - 72 = 1, write 8 in the quotient.
- Bring down the 5, now divide 15 by 9.
- 9 × 1 = 9, subtract 15 - 9 = 6, write 1 in the quotient.
- 6 is less than 9, so remainder = 6.
- The quotient is 81 with remainder 6.
This method also extends to decimals and larger numbers. Division is essentially splitting a number into equal parts or groups, and long division helps manage that process step-by-step with large numbers.
