Find how many complete days fit into 139 hours.
Divide 139 hours by 86,400:
139 ÷ 86,400 = 5.791666666667
This means 139 hours contains5 full days, plus a little extra time.

Find how many seconds are left.
We know that 5 days contain:
5 × 86,400= 432,000 seconds
We started with 500,400 seconds. Subtract the seconds we've already used:
500,400 − 432,000= 68,400 seconds
That leaves 68,400 seconds after counting the 5 full days.
Final answer
139 hours = 5 days and 68,400 seconds
5 full days + 68,400 seconds left over.
