You might find this a bit more readable:
Code:
awk '{if($1==0)print 0; else print $2/$1}' infile

I'm wondering how did you get rid off float problem ?

Old 12-28-2010
What float problem were you experiencing? Could you give an example of that?

I'm getting output like this

Code:
4.04149e-06	1.41442e-06
2.88758e-06	3.37641e-06

Is it possible to change them to normal integer format

Do you mean like this, for example?
Code:
awk '{printf "%.2f\n",$1?$2/$1:0}' infile

yes. but i have many columns. so i used htis instead of your style and didn't work. but it suppose to work ?

Code:
awk '{print $1?$2/$1:0}' OFMS='%0.2f' infile
