  1. 12345/60 = 205.75, which means 205 minutes and some remainder in seconds. One what to find the remainder is 12345-205*60 = 45, so we have 205 minutes, 45 seconds as the partial answer.

    205/60 - 3.146666..., so this means it turns into 3 hours and a remainder of minutes 205-3*60 = 25, so the final answer is 3 hours, 25 minutes and 45 seconds.

    (Thanks to Phillip Barringer for making a correction.)

    1776/60 = 29.6, so we can find the remainder as 1776-29*60 = 36 minutes. 29 hours is 1 day and 5 hours so the final answer is 1 day, 5 hours and 36 minutes.
