Step-by-Step Explanation
Here's how to solve 810 ÷ 45 using long division method step by step:
Step 1:Take the number 81 and divide by 45. We get 1 (write it in the quotient). Multiply 1 × 45 = 45 (write it below the dividend). Subtract 81 - 45 = 36. The remainder 36 is carried to the next step.
Step 2:Take the number 360 and divide by 45. We get 8 (write it in the quotient). Multiply 8 × 45 = 360 (write it below the dividend). Subtract 360 - 360 = 0.
Final Step:The division is complete with no remainder. 810 divides exactly by 45 to give 18.
Division Steps
| Step | Dividend Part | Quotient Digit | Multiply | Subtract | Remainder |
|---|---|---|---|---|---|
| 1 | 81 | 1 | 1 × 45 = 45 | 81 - 45 = 36 | 36 |
| 2 | 360 | 8 | 8 × 45 = 360 | 360 - 360 = 0 | 0 |
Perfect division: 810 divides evenly by 45 with no remainder.
About Long Division
Long division is a method for dividing large numbers that breaks down the division process into smaller, manageable steps. It's taught in elementary school as a systematic way to perform division by hand.
The process involves:
- Dividing the leftmost digits of the dividend by the divisor
- Writing the quotient digit above the dividend
- Multiplying the quotient digit by the divisor
- Subtracting this product from the current dividend portion
- Bringing down the next digit and repeating the process
This method ensures accuracy and helps students understand the relationship between multiplication and division.
