Step-by-Step Explanation
Here's how to solve 21000 ÷ 4 using long division method step by step:
Step 1:Take the number 21 and divide by 4. We get 5 (write it in the quotient). Multiply 5 × 4 = 20 (write it below the dividend). Subtract 21 - 20 = 1. The remainder 1 is carried to the next step.
Step 2:Take the number 10 and divide by 4. We get 2 (write it in the quotient). Multiply 2 × 4 = 8 (write it below the dividend). Subtract 10 - 8 = 2. The remainder 2 is carried to the next step.
Step 3:Take the number 20 and divide by 4. We get 5 (write it in the quotient). Multiply 5 × 4 = 20 (write it below the dividend). Subtract 20 - 20 = 0.
Step 4:Number 0 is less than divisor 4, so we write 0 in the quotient and move to the next digit.
Final Step:The division is complete with no remainder. 21000 divides exactly by 4 to give 5250.
Division Steps
| Step | Dividend Part | Quotient Digit | Multiply | Subtract | Remainder |
|---|---|---|---|---|---|
| 1 | 21 | 5 | 5 × 4 = 20 | 21 - 20 = 1 | 1 |
| 2 | 10 | 2 | 2 × 4 = 8 | 10 - 8 = 2 | 2 |
| 3 | 20 | 5 | 5 × 4 = 20 | 20 - 20 = 0 | 0 |
| 4 | 0 | 0 | 0 × 4 = 0 | 0 - 0 = 0 | 0 |
Perfect division: 21000 divides evenly by 4 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.
