Long Division Method

Long division is a technique used to break down large numbers into manageable steps, simplifying the division process into a series of sequential steps. It is widely employed as the primary method for solving division problems.

  • Step 1: Begin by taking the leftmost digit of the dividend (81). Verify if this digit is greater than or equal to the divisor (4).
  • Step 2: Divide this digit by the divisor and record the quotient above.
  • Step 3: Subtract the product of the division from the original digit and note the difference below.
  • Step 4: If there are additional digits in the dividend, bring down the next one.
  • Step 5: Repeat the same process.
