Step-by-Step Explanation

Here's how to solve 30 ÷ 2 using long division method step by step:

Step 1:Take the number 3 and divide by 2. We get 1 (write it in the quotient). Multiply 1 × 2 = 2 (write it below the dividend). Subtract 3 - 2 = 1. The remainder 1 is carried to the next step.
Step 2:Take the number 10 and divide by 2. We get 5 (write it in the quotient). Multiply 5 × 2 = 10 (write it below the dividend). Subtract 10 - 10 = 0.
Final Step:The division is complete with no remainder. 30 divides exactly by 2 to give 15.

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.
