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 2056, we need to group it as 56 and 20.

Step 2: Now we need to find n whose square is ≤ 20. We can say n is '4' because 4 x 4 = 16, which is less than 20. Now the quotient is 4; after subtracting 16 from 20, the remainder is 4.

Step 3: Now let us bring down 56, which is the new dividend. Add the old divisor with the same number: 4 + 4 = 8, which will be our new divisor.

Step 4: The new divisor will be the sum of 8 and n. We need to find a digit n where 8n x n ≤ 456.

Step 5: The next step is finding n. Let us consider n as 5, now 85 x 5 = 425.

Step 6: Subtract 425 from 456; the difference is 31, and the quotient is 45.

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 3100.

Step 8: Now we need to find the new divisor: 450 + n, where 450n x n ≤ 3100. Let us consider n as 6, now 456 x 6 = 2736.

Step 9: Subtracting 2736 from 3100, we get the result 364.

Step 10: Now the quotient is 45.3.

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 √2056 is approximately 45.33.
