Step-by-Step Explanation
Here's how to solve 1620 ÷ 90 using long division method step by step:
Step 1:Take the number 162 and divide by 90. We get 1 (write it in the quotient). Multiply 1 × 90 = 90 (write it below the dividend). Subtract 162 - 90 = 72. The remainder 72 is carried to the next step.
Step 2:Take the number 720 and divide by 90. We get 8 (write it in the quotient). Multiply 8 × 90 = 720 (write it below the dividend). Subtract 720 - 720 = 0.
Final Step:The division is complete with no remainder. 1620 divides exactly by 90 to give 18.
Division Steps
| Step | Dividend Part | Quotient Digit | Multiply | Subtract | Remainder |
|---|---|---|---|---|---|
| 1 | 162 | 1 | 1 × 90 = 90 | 162 - 90 = 72 | 72 |
| 2 | 720 | 8 | 8 × 90 = 720 | 720 - 720 = 0 | 0 |
Perfect division: 1620 divides evenly by 90 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.
