a is known, b is known, you want to know c.
So you divide both sides by c.
a/c=b X c / c
The X c/c cancel each other out and you get
a/c=b
How can I divide a by c when I don't know what c is?
The known on the left hand side, the unknown on the right hand side.
A/b=c

No problem, it's called thread wandering, you do it for fun. Sometimes it's surprising where you end up.
