The division method (also known as the long division method) for finding the square root of a number involves these steps:

### Step-by-Step: Finding the Square Root of 256

1. **Group the digits in pairs**:
   Group the digits of 256 starting from the right. Since 256 is a three-digit number, group it as (2)(56).

2. **Find the largest square**:
   Find the largest square number less than or equal to the leftmost group. In this case, for the group "2", the largest square is \(1^2 = 1\). Subtract 1 from 2 to get the remainder:  
   \( 2 - 1 = 1 \).

3. **Bring down the next pair**:
   Bring down the next pair of digits, "56". Now we have 156.

4. **Double the quotient**:
   The current quotient is 1, so double it to get 2. Write this as the first part of the divisor.

5. **Find the next digit of the quotient**:
   Find a digit \(x\) such that when you append \(x\) to the divisor (i.e., 2 becomes 2x) and multiply by \(x\), the result is as close as possible to 156 but not greater. In this case, \(x = 6\), because \(26 \times 6 = 156\).

6. **Subtract and bring down the next pair**:
   Subtract 156 from 156 to get 0, and there are no more digits to bring down.

The quotient we get is 16, so the square root of 256 is **16**.

### Conclusion
Thus, \( \sqrt{256} = 16 \).
