To find the square root of a number, you can either use a calculator or apply the following method:

1. Start with the number you want to find the square root of, in this case, 16.
2. Take an initial guess for the square root. Let's start with 4 (since 4 squared is 16).
3. Divide the original number by your guess: 16 ÷ 4 = 4.
4. Average the result obtained from step 3 with your initial guess: (4 + 4) ÷ 2 = 4.
5. Repeat steps 3 and 4 until you get a result that is accurate enough.
- Take the result from step 4 (4) and divide the original number by it: 16 ÷ 4 = 4.
- Average the result with your previous guess: (4 + 4) ÷ 2 = 4.
