The greatest three-digit number which is a perfect square is 961. Since 999 is the largest three-digit number. Now use the long division method to calculate the square root of 999.
Hence, the greatest three-digit number which is a perfect square = 999 – 38 = 961. Long division in mathematics is a strategy for breaking down complicated division problems into a series of simpler steps. It is the approach that division-based issues are typically solved using.

Components of Long Division
We must be aware of the key components of long division when doing long division. The following is a list of the fundamental components of long division:
- Dividend
- Divisor
- Quotient
- Remainder
Steps in Long Division
A vinculum separates the dividend from the quotient, while a right parenthesis or vertical bar separates the divisor from the dividend (an overbar). Let’s now go through the long division steps listed below to comprehend the procedure.
Step 1: Take the dividend’s first digit starting from the left in step one. Verify if this digit exceeds or is equal to the divisor.
Step 2: The result should be written as the quotient on top after being divided by the divisor.
Step 3: Subtract the outcome from the digit, and then put the difference below.
Step 4: Decrease the dividend’s subsequent digit (if present).
Step 5: Carry out Step 4 again.
Summary:
