Step-by-Step Explanation
Here's how to solve 90 ÷ 23 using long division method step by step:
Step 1:Take the number 90 and divide by 23. We get 3 (write it in the quotient). Multiply 3 × 23 = 69 (write it below the dividend). Subtract 90 - 69 = 21. The remainder 21 is carried to the next step.
Final Step:The remainder 21 is smaller than the divisor 23, so the division is complete. The final answer is 3 with remainder 21.
Division Steps
| Step | Dividend Part | Quotient Digit | Multiply | Subtract | Remainder |
|---|---|---|---|---|---|
| 1 | 90 | 3 | 3 × 23 = 69 | 90 - 69 = 21 | 21 |
Final remainder: 21
Since 21 is less than 23, we cannot divide further. The final answer is 3 with remainder 21.
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.
