Step-by-Step Explanation

Here's how to solve 640 ÷ 5 using long division method step by step:

Step 1:Take the number 6 and divide by 5. We get 1 (write it in the quotient). Multiply 1 × 5 = 5 (write it below the dividend). Subtract 6 - 5 = 1. The remainder 1 is carried to the next step.
Step 2:Take the number 14 and divide by 5. We get 2 (write it in the quotient). Multiply 2 × 5 = 10 (write it below the dividend). Subtract 14 - 10 = 4. The remainder 4 is carried to the next step.
Step 3:Take the number 40 and divide by 5. We get 8 (write it in the quotient). Multiply 8 × 5 = 40 (write it below the dividend). Subtract 40 - 40 = 0.
Final Step:The division is complete with no remainder. 640 divides exactly by 5 to give 128.

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.
