Step-by-Step Explanation

Here's how to solve 312 ÷ 3 using long division method step by step:

Step 1: Take the number 3 and divide by 3. We get 1 (write it in the quotient). Multiply 1 × 3 = 3 (write it below the dividend). Subtract 3 - 3 = 0.
Step 2: Number 1 is less than divisor 3, so we write 0 in the quotient and move to the next digit.
Step 3: Take the number 12 and divide by 3. We get 4 (write it in the quotient). Multiply 4 × 3 = 12 (write it below the dividend). Subtract 12 - 12 = 0.
Final Step: The division is complete with no remainder. 312 divides exactly by 3 to give 104.

Perfect division: 312 divides evenly by 3 with no remainder.

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.
