Step-by-Step Explanation
Here's how to solve 21 ÷ 19 using long division method step by step:
Step 1:Take the number 21 and divide by 19. We get 1 (write it in the quotient). Multiply 1 × 19 = 19 (write it below the dividend). Subtract 21 - 19 = 2. The remainder 2 is carried to the next step.
Final Step:The remainder 2 is smaller than the divisor 19, so the division is complete. The final answer is 1 with remainder 2.
Division Steps
| Step | Dividend Part | Quotient Digit | Multiply | Subtract | Remainder |
|---|---|---|---|---|---|
| 1 | 21 | 1 | 1 × 19 = 19 | 21 - 19 = 2 | 2 |
Final remainder: 2
Since 2 is less than 19, we cannot divide further. The final answer is 1 with remainder 2.
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.
