    \frac{621}{0.31} = \frac{62100}{31}

    Now do your division.

    I get 2003.2258064516

    Now, the third decimal place is a 5, and there are numbers past this. So by the way I was taught, we round up the second decimal place:
    \frac{621}{0.31} = 2003.23

    (If it had turned out to be exactly 2003.225 I would round down to 2003.22.)
