I divided 4.18 by 5 by hand, like this:
As you see I removed the decimal point since I was dividing by a whole number, then I put the decimal point back and got 0.83 as result.
It's correct, the point is that often on this kind of division I get a remainder (in this case is 3), and I suppose this isn't right.
By the way, a calculator returns 0.836 for 4.18/5, which means I'm missing at least one decimal place.
My question is, how do I solve division with decimal points so that I get all the decimal places. Is it ok to have a remainder?
