Step-by-Step Explanation
Here's how to solve 1005 ÷ 80 using long division method step by step:
Step 1:Take the number 100 and divide by 80. We get 1 (write it in the quotient). Multiply 1 × 80 = 80 (write it below the dividend). Subtract 100 - 80 = 20. The remainder 20 is carried to the next step.
Step 2:Take the number 205 and divide by 80. We get 2 (write it in the quotient). Multiply 2 × 80 = 160 (write it below the dividend). Subtract 205 - 160 = 45. The remainder 45 is carried to the next step.
Final Step:The remainder 45 is smaller than the divisor 80, so the division is complete. The final answer is 12 with remainder 45.
Division Steps
| Step | Dividend Part | Quotient Digit | Multiply | Subtract | Remainder |
|---|---|---|---|---|---|
| 1 | 100 | 1 | 1 × 80 = 80 | 100 - 80 = 20 | 20 |
| 2 | 205 | 2 | 2 × 80 = 160 | 205 - 160 = 45 | 45 |
Final remainder: 45
Since 45 is less than 80, we cannot divide further. The final answer is 12 with remainder 45.
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.
