Step-by-Step Explanation
Here's how to solve 285 ÷ 15 using long division method step by step:
Step 1:Take the number 28 and divide by 15. We get 1 (write it in the quotient). Multiply 1 × 15 = 15 (write it below the dividend). Subtract 28 - 15 = 13. The remainder 13 is carried to the next step.
Step 2:Take the number 135 and divide by 15. We get 9 (write it in the quotient). Multiply 9 × 15 = 135 (write it below the dividend). Subtract 135 - 135 = 0.
Final Step:The division is complete with no remainder. 285 divides exactly by 15 to give 19.
Division Steps
| Step | Dividend Part | Quotient Digit | Multiply | Subtract | Remainder |
|---|---|---|---|---|---|
| 1 | 28 | 1 | 1 × 15 = 15 | 28 - 15 = 13 | 13 |
| 2 | 135 | 9 | 9 × 15 = 135 | 135 - 135 = 0 | 0 |
Perfect division: 285 divides evenly by 15 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.
