Step-by-Step Explanation
Here's how to solve 1280 ÷ 2 using long division method step by step:
Step 1:Take the number 12 and divide by 2. We get 6 (write it in the quotient). Multiply 6 × 2 = 12 (write it below the dividend). Subtract 12 - 12 = 0.
Step 2:Take the number 8 and divide by 2. We get 4 (write it in the quotient). Multiply 4 × 2 = 8 (write it below the dividend). Subtract 8 - 8 = 0.
Step 3:Number 0 is less than divisor 2, so we write 0 in the quotient and move to the next digit.
Final Step:The division is complete with no remainder. 1280 divides exactly by 2 to give 640.
Division Steps
| Step | Dividend Part | Quotient Digit | Multiply | Subtract | Remainder |
|---|---|---|---|---|---|
| 1 | 12 | 6 | 6 × 2 = 12 | 12 - 12 = 0 | 0 |
| 2 | 8 | 4 | 4 × 2 = 8 | 8 - 8 = 0 | 0 |
| 3 | 0 | 0 | 0 × 2 = 0 | 0 - 0 = 0 | 0 |
Perfect division: 1280 divides evenly by 2 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.
