If you divide 39 by 43 in a calculator, you will receive the decimal representation.
To 7 decimal places, 0.9069767
how do you change a 39/43 in to a decimal and also how do you do long division? sorry for keeping on changing it! again
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.
