Find how many seconds are left.
We know that 16 years contain:
16 × 31,536,000= 504,576,000 seconds
We started with 508,032,000 seconds. Subtract the seconds we've already used:
508,032,000 − 504,576,000= 3,456,000 seconds
That leaves 3,456,000 seconds after counting the 16 full years.
Final answer
840 weeks = 16 years and 3,456,000 seconds
16 full years + 3,456,000 seconds left over.
