Float is 0 after integer division

It might be a simple solution but I can not fix it.

I am dividing 2 integers :

finishedGameFinalScore = [score integerValue];
CGFloat interval = 2/finishedGameFinalScore;
NSLog(@"interval = %f",interval);

The log returns 0.000000

Is there a limit for decimal places? I need to preserve the decimal result.

Thanks Shani
