Step-by-Step Explanation

Here's how to solve 81 ÷ 4 using long division method step by step:

Step 1:Take the number 8 and divide by 4. We get 2 (write it in the quotient). Multiply 2 × 4 = 8 (write it below the dividend). Subtract 8 - 8 = 0.
Step 2:Number 1 is less than divisor 4, so we write 0 in the quotient and move to the next digit.
Final Step:The remainder 1 is smaller than the divisor 4, so the division is complete. The final answer is 20 with remainder 1.

2100 × 4 = 01 - 0 = 11

Final remainder: 1

Since 1 is less than 4, we cannot divide further. The final answer is 20 with remainder 1.

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.
