I do this:
select 18/94
and got 0!
answer is supposed to be .19. I tried
select convert(decimal(5,2), 18.94)
and still got 0.00.
I don't understand!

You got zero (0) because you are doing integer division. Try this: select 18/19. -- << be sure to include the decimal point at the end.

select 18/19 still gives me zero.

Someone, please show me how to divide integers so that 94/18 gives me .19

I know I've done this before and can't understand where this is coming from.

I just want to be able to divide.

select 18 * 1.0/94

too late, I figured it out. Each number has to be divided seperately.

select cast(18 as float)/cast(19 as float);

select convert(decimal(5,2),18)/convert(decimal(5,2), 19);

Spare me the long winding road to nowhere

FWIW - you only need to cast/convert one of those values in order for it to work properly.

You can also shorthand it like Scott and Lynn showed as well.
