Try and use some math notation, especially with whacky numbers. It makes it shorter and they don't get lost in the paragraph.
EDIT: I think I understand your question now. It's basically, how many Coloumbs, do X electrons make right? Well, you said that there are Y electrons/C, and you have X electrons. Therefore you must go
X/Y = Z[Coloumbs].
That's the way the units cancel out which verifies it is correct. You are just grouping the electrons into Coloumbs.
It's like saying, if I have 36, and 12 is a dozen, how many dozens do I have? 36/12 = 3.
