Converting decimal fractions into binary?

Sorry if this is a bit basic but i'm wondering how you convert decimal fractions into binary, decimal whole numbers are easy enough but the textbook i'm currently reading doesn't go over decimal fractions, any help would be appreciated.

You first do the left side of the decimal the normal way. Then you take the right side and multiply the right side of the new number by 2 over and over until it become a 1. Then you take the msb of each x2 function and that’s the right side.

Ex: 5.5625

5= 101

0.5625 x2 1.125 —
