How do I divide in the Linux console?

Question

I have to variables and I want to find the value of one divided by the other. What commands should I use to do this?

Answer 1

I still prefer using dc, which is an RPN calculator, so quick session to divide 67 by 18 with 4 digits precision would look like

>dc
4k
67
18/p
3.7222
q
>

Obviously, much more available: man dc
