I'll go over the guess and divide method.
Let's assume X is the number we want the square root of.
The guess and divide consists of:
1. Guessing the square root of X (the guess is now known as Y1).
2. Divide X by Y1, and then using the resulting number as the new Y2.
3. Average Y1 and Y2, giving you the new number Y1.
4. Repeat steps 2-3 until your guess Y1 is roughly equal to the average of Y1 and Y2
Here's an example
sqrt 695; my first guess for the root is 25.
1. 695 / 25 = 27.8
2. 25 + 27.8 / 2 = 26.4
3. 695 / 26.4 = 26.3257
4. 26.4 + 26.3257 / 2 = 26.36285
5. 695 / 26.36285 = 26.3628553
These two numbers are about equal, so you now have a good estimate of the root of 695. 26.3628553 *26.3628553 = 695.0001 You can keep going through the process until you are satisfied with the accuracy.

How do you know whether a number is a perfect square?
A number is a perfect square when you can directly extract its square root in whole numbers and without approximation. When you subject a certain number to a radical sign, you can extract its square. Example: 25 is a perfect square. it's square root is 5, since 5 x 5 is equal to 25
How can a make a batch file to know if a number is not a perfect square?

What is the difference between principal square root and perfect square root?
A principal square root is any square root that's answer is positive, and a perfect square root is a square root that's answer is an integer.

What is the square root of a square that has no root?
It's not a square if it has no root. If a number is a square then, by definition, it MUST have a square root. If it did not it would not be a square.
