It's so mysterious . how it gives the correct answer ?

It's easy to understand, when you do the process you will always get a number which can be divided by 9 so it always be a multiple of 9 and if you look at the all multiples of 9, you will find out all of them have same shape. The above statement has a mathematical proof.
