## Main Question or Discussion Point

Hello everyone, I realize this is really basic stuff and mainly pointless considering calculators can do it for you but i'm still wondering on why this isn't working out right. I'm in a digital design class and he showed us a method for converting decimal to binary and it seemed easy and seemed to work great but he would use numbers such as: 25 and nothing that had a decimal point. Well the number is 369.3125 decimal. To convert to binary it worked fine for the whole number 369 by just divding by the desired base, so since i wanted binary, i would divide by 2 and the remainder of each would be the number in binary. Also if I wanted to convert decimal to octal, i could just keep on divding by 8, and so on. But as you can see I can't figure it out how you figure out the .3125 of the number by using the divding method? Also I'm having troubles converting it to octal using the dividing method. Here is my work in the picture. Any help would be great!
