There are 60 seconds in a minute and 60 minutes in an hour.

Hence:

1 minute = 60 s
1 hour = 3600 seconds.

So the first thing to do is divide your total amount be 3600, and then subtract the remainder, and that is how many hours have passed:

$\frac{2586}{3600} < 1$ So no hours pass.

Note divide your number by 60 to see how many hours pass:

$\frac{2586}{60} = 43.1$, so 43 minutes have passed.

Now how many seconds? WEll the remainder from the minutes was 0.1. So what is 0.1 minutes in seconds??

$0.1\text{ minutes} = 0.1 \times 60 \text{ seconds} = 6 \text{ seconds}$

So 43 minutes and 6 seconds have passed.
