Operations on integer arguments will return an integer result. To get
the value you're expecting from that division, you'll need to cast one
of the numbers to a floating point type.
Any of the following will produce the result you wanted:
select cast(30 as real) / 50;
select cast(30 as numeric) / 50;
select 30::real / 50;
select 30 / 50::float;
As well as any other variations along that theme.
