    If you divide 39 by 43 in a calculator, you will receive the decimal representation.

    To 7 decimal places, 0.9069767

    it depends upon how many digits you want, kind of.

    So for your problem you could do this:

    Its obvious that (39/43) = (1/10)*(390/43) = (1/100)*(3900/43) = ...

    So you can multiply 39 by, say, 10,000 and then do regular long division, and then divide your answer by 10,000 at the end.
