Step-by-Step Explanation
Here's how to solve 45 ÷ 3 using long division method step by step:
Step 1:Take the number 4 and divide by 3. We get 1 (write it in the quotient). Multiply 1 × 3 = 3 (write it below the dividend). Subtract 4 - 3 = 1. The remainder 1 is carried to the next step.
Step 2:Take the number 15 and divide by 3. We get 5 (write it in the quotient). Multiply 5 × 3 = 15 (write it below the dividend). Subtract 15 - 15 = 0.
Final Step:The division is complete with no remainder. 45 divides exactly by 3 to give 15.
Division Steps
| Step | Dividend Part | Quotient Digit | Multiply | Subtract | Remainder |
|---|---|---|---|---|---|
| 1 | 4 | 1 | 1 × 3 = 3 | 4 - 3 = 1 | 1 |
| 2 | 15 | 5 | 5 × 3 = 15 | 15 - 15 = 0 | 0 |
Perfect division: 45 divides evenly by 3 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.
