Surprisingly, it seems to work properly in **Windows PowerShell** *(version 3)*.

 PS C:\> 1.0 / 6.0
 0.166666666666667
 
 PS C:\> 1/6
 0.166666666666667

Also seems to work in Python 3 as sepp2k mentioned. The other two languages I have readily available on REPL, Scala and Ruby, both do integer division and yield 0.
