Step-by-Step Explanation

Here's how to solve 3,900 ÷ 45 using long division method step by step:

Step 1:Take the number 390 and divide by 45. We get 8 (write it in the quotient). Multiply 8 × 45 = 360 (write it below the dividend). Subtract 390 - 360 = 30. The remainder 30 is carried to the next step.
Step 2:Take the number 300 and divide by 45. We get 6 (write it in the quotient). Multiply 6 × 45 = 270 (write it below the dividend). Subtract 300 - 270 = 30. The remainder 30 is carried to the next step.
Final Step:The remainder 30 is smaller than the divisor 45, so the division is complete. The final answer is 86 with remainder 30.

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.
