Step-by-Step Explanation

Here's how to solve 21000 ÷ 12 using long division method step by step:

Step 1:Take the number 21 and divide by 12. We get 1 (write it in the quotient). Multiply 1 × 12 = 12 (write it below the dividend). Subtract 21 - 12 = 9. The remainder 9 is carried to the next step.
Step 2:Take the number 90 and divide by 12. We get 7 (write it in the quotient). Multiply 7 × 12 = 84 (write it below the dividend). Subtract 90 - 84 = 6. The remainder 6 is carried to the next step.
Step 3:Take the number 60 and divide by 12. We get 5 (write it in the quotient). Multiply 5 × 12 = 60 (write it below the dividend). Subtract 60 - 60 = 0.
Step 4:Number 0 is less than divisor 12, 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 12 to give 1750.

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.
