The long division method is particularly used for non-perfect square numbers. In this method, we should check the closest perfect square number for the given number. Let us now learn how to find the square root using the long division method, step by step.

Step 1: To begin with, we need to group the numbers from right to left. In the case of 366, we need to group it as 66 and 3.

Step 2: Now we need to find n whose square is 3. We can say n as ‘1’ because 1 x 1 is less than or equal to 3. Now the quotient is 1; after subtracting 1 from 3, the remainder is 2.

Step 3: Now let us bring down 66, which is the new dividend. Add the old divisor with the same number 1 + 1; we get 2, which will be our new divisor.

Step 4: The new divisor will be the sum of the dividend and quotient. Now we get 2n as the new divisor; we need to find the value of n.

Step 5: The next step is finding 2n x n ≤ 266. Let us consider n as 9; now 2 x 9 x 9 = 162.

Step 6: Subtract 266 from 162; the difference is 104, and the quotient is 19.

Step 7: Since the dividend is less than the divisor, we need to add a decimal point. Adding the decimal point allows us to add two zeroes to the dividend. Now the new dividend is 10400.

Step 8: Now we need to find the new divisor that is 381 because 381 x 9 = 3429.

Step 9: Subtracting 3429 from 10400, we get the result 6971.

Step 10: Now the quotient is 19.1

Step 11: Continue doing these steps until we get two numbers after the decimal point. Suppose if there are no decimal values, continue till the remainder is zero.

So the square root of √366 is approximately 19.10.
