convert integer to mm:ss

Is there a way to convert an integer that is already in seconds to mm:ss?

For example, I have two integers I have divided [sum(x)/sum(y)] to get a total talk time in seconds of 188.90780

If I wanted to get the minutes, I'd divide by 60, so... 188.9078 / 60 = 3.14846

The decimal basically translates to .14846 * 60s = 8.9076 ~ 9 seconds

My answer should bring 3.9 or 3 minutes 9 seconds.

I figured out a way to do this, but it is a really, really long calc that works best as a string and I'm sure someone has a better idea on here.

str(float(left(str((sum([x])/sum([y]))/60),1)))

+"m, "+

str(

if float(left(str((float(str((sum([x])/sum([y]))/60))-float(left(str((sum([x])/sum([y]))/60),1)))*60),2))>10

then

left(str((float(str((sum([x])/sum([y]))/60))-float(left(str((sum([x])/sum([y]))/60),1)))*60),2)

else

left(str((float(str((sum([x])/sum([y]))/60))-float(left(str((sum([x])/sum([y]))/60),1)))*60),1)

end)

+ "s"

See what I mean?
