First you need to round. Rounding is simple. If the number in the previous place is 4 or less you just make it a zero. If the previous place is 5 or more, you round up. So since we are round to the hundreds place, we can forget about any number that is past the hundreds place for now. To start rounding, you start furthest to the right or the smallest digit. Then you follow the process stated above.
656 ⇒ 660
660 ⇒ 700
Now that we have the rounded number, we divide by the given number which is 80.
