Step-by-Step Explanation
Here's how to solve 100005 ÷ 45 using long division method step by step:
Step 1:Take the number 100 and divide by 45. We get 2 (write it in the quotient). Multiply 2 × 45 = 90 (write it below the dividend). Subtract 100 - 90 = 10. The remainder 10 is carried to the next step.
Step 2:Take the number 100 and divide by 45. We get 2 (write it in the quotient). Multiply 2 × 45 = 90 (write it below the dividend). Subtract 100 - 90 = 10. The remainder 10 is carried to the next step.
Step 3:Take the number 100 and divide by 45. We get 2 (write it in the quotient). Multiply 2 × 45 = 90 (write it below the dividend). Subtract 100 - 90 = 10. The remainder 10 is carried to the next step.
Step 4:Take the number 105 and divide by 45. We get 2 (write it in the quotient). Multiply 2 × 45 = 90 (write it below the dividend). Subtract 105 - 90 = 15. The remainder 15 is carried to the next step.
Final Step:The remainder 15 is smaller than the divisor 45, so the division is complete. The final answer is 2222 with remainder 15.
Division Steps
| Step | Dividend Part | Quotient Digit | Multiply | Subtract | Remainder |
|---|---|---|---|---|---|
| 1 | 100 | 2 | 2 × 45 = 90 | 100 - 90 = 10 | 10 |
| 2 | 100 | 2 | 2 × 45 = 90 | 100 - 90 = 10 | 10 |
| 3 | 100 | 2 | 2 × 45 = 90 | 100 - 90 = 10 | 10 |
| 4 | 105 | 2 | 2 × 45 = 90 | 105 - 90 = 15 | 15 |
Final remainder: 15
Since 15 is less than 45, we cannot divide further. The final answer is 2222 with remainder 15.
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.
