Calculating Elapsed Time

I'm having trouble calculating elapsed time. I want the answer to state
the number of days, hour, and minutes. In Column E I can get the number
of hours but how do I parse this value to get Hours, days, minutes? I also need to divide the hours into days (ex. 1506/24)

Thank you,

Formula in E is =D2-(B2+C2).

Thank you.
