Step-by-Step Explanation
Here's how to solve 42 ÷ 1 using long division method step by step:
Step 1:Take the number 4 and divide by 1. We get 4 (write it in the quotient). Multiply 4 × 1 = 4 (write it below the dividend). Subtract 4 - 4 = 0.
Step 2:Take the number 2 and divide by 1. We get 2 (write it in the quotient). Multiply 2 × 1 = 2 (write it below the dividend). Subtract 2 - 2 = 0.
Final Step:The division is complete with no remainder. 42 divides exactly by 1 to give 42.
Division Steps
| Step | Dividend Part | Quotient Digit | Multiply | Subtract | Remainder |
|---|---|---|---|---|---|
| 1 | 4 | 4 | 4 × 1 = 4 | 4 - 4 = 0 | 0 |
| 2 | 2 | 2 | 2 × 1 = 2 | 2 - 2 = 0 | 0 |
Perfect division: 42 divides evenly by 1 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.
