Step-by-Step Explanation

Here's how to solve 9999979 ÷ 20 using long division method step by step:

Step 1:Take the number 99 and divide by 20. We get 4 (write it in the quotient). Multiply 4 × 20 = 80 (write it below the dividend). Subtract 99 - 80 = 19. The remainder 19 is carried to the next step.
Step 2:Take the number 199 and divide by 20. We get 9 (write it in the quotient). Multiply 9 × 20 = 180 (write it below the dividend). Subtract 199 - 180 = 19. The remainder 19 is carried to the next step.
Step 3:Take the number 199 and divide by 20. We get 9 (write it in the quotient). Multiply 9 × 20 = 180 (write it below the dividend). Subtract 199 - 180 = 19. The remainder 19 is carried to the next step.
Step 4:Take the number 199 and divide by 20. We get 9 (write it in the quotient). Multiply 9 × 20 = 180 (write it below the dividend). Subtract 199 - 180 = 19. The remainder 19 is carried to the next step.
Step 5:Take the number 197 and divide by 20. We get 9 (write it in the quotient). Multiply 9 × 20 = 180 (write it below the dividend). Subtract 197 - 180 = 17. The remainder 17 is carried to the next step.
Step 6:Take the number 179 and divide by 20. We get 8 (write it in the quotient). Multiply 8 × 20 = 160 (write it below the dividend). Subtract 179 - 160 = 19. The remainder 19 is carried to the next step.
Final Step:The remainder 19 is smaller than the divisor 20, so the division is complete. The final answer is 499998 with remainder 19.

Since 19 is less than 20, we cannot divide further. The final answer is 499998 with remainder 19.

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.
