There are 24 hours to a day, so you can write this as
704 days, 11 hours = 704 + 11/24 days
Then dividing by 29 gives
704/29 + 11/696 days
We have
704 = 24*29 + 8
so that the time is equal to
24 + 8/29 + 11/696 days
24 + (192 + 11)/696 days
24 + 7/24 days
which in terms of days and hours is
24 days, 7 hours
