Step-by-Step Explanation
Here's how to solve 638 ÷ 2 using long division method step by step:
Step 1:Take the number 6 and divide by 2. We get 3 (write it in the quotient). Multiply 3 × 2 = 6 (write it below the dividend). Subtract 6 - 6 = 0.
Step 2:Take the number 3 and divide by 2. We get 1 (write it in the quotient). Multiply 1 × 2 = 2 (write it below the dividend). Subtract 3 - 2 = 1. The remainder 1 is carried to the next step.
Step 3:Take the number 18 and divide by 2. We get 9 (write it in the quotient). Multiply 9 × 2 = 18 (write it below the dividend). Subtract 18 - 18 = 0.
Final Step:The division is complete with no remainder. 638 divides exactly by 2 to give 319.
Division Steps
| Step | Dividend Part | Quotient Digit | Multiply | Subtract | Remainder |
|---|---|---|---|---|---|
| 1 | 6 | 3 | 3 × 2 = 6 | 6 - 6 = 0 | 0 |
| 2 | 3 | 1 | 1 × 2 = 2 | 3 - 2 = 1 | 1 |
| 3 | 18 | 9 | 9 × 2 = 18 | 18 - 18 = 0 | 0 |
Perfect division: 638 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.
