Decimal Places Difficulty

The exchange between you and Wyn Hopkins points up a real irony here. You describe yourself as a basic user of Excel, yet you were assuming that there had to be a "fancy" solution to the division of one number by another. In fact, at the most basic level you've got all of the basic arithmetic functions we learned in primary school:
ADDITION by =A1+B1
SUBTRACTION by =A1-B1
MULTIPLICATION by =A1*B1 (granted, in primary school we used "x")
DIVISION by =A1/B1

Now, because it's very common to add a whole series of numbers, usually in a column, they've included a fairly basic function called SUM, as in =SUM(A1:Z1)

Anyway, I'm writing just to say, Excel has a lot of power, a LOT, but as you've discovered, it can backfire if you don't take the time to actually read a little bit. When you get a result that doesn't make sense--as you were--go back and look at the description (use the "Help" menu and search for the name of the function used)....

To make you feel better here, I've been using Excel since (in a sense) before it existed. I began programming on mainframes in the early '70s, moved quickly to PCs when they became available, used in succession, Lotus 1-2-3, Quattro (few remember it), and then Excel in all its generations. BUT, here's where you can find some relief, until your question was posted here, I'd never heard of the QUOTIENT function (it's relatively new). So thank you for adding to my knowledge of Excel.
