Okay,
6*322=1932
1960-1932=28
28/322=.08
A remainder is not to be put in a decimal expansion of a fraction. It must be considered in relation to the denominator, ie. divide it by 322. Continue as necessary...
Yeah, I'm not in middle school but I ought to be... Studying for the GMAT and I can't figure out this flippin division question and could use some assistance.
I keep coming up with 6.028 but the answer is 6.09, as any math calculator will tell you.
How is the question...
It starts with:
19.6 / 3.22 (which is supposed to = 6.09 - but how?)
I then converted it to:
1960 / 322
But I come up with this:
1960 / 322
322 x 6 = 1932
1960 - 1932 = 28
Add in the decimals, blah, blah... And that's what I got.
Are there any good math calculators online that actually show the work?

Here is a nice tutorial on what to do.
Long Division With Remainders
And, from the same site, dealing with decimal places specifically:
Division with Decimals
This is only a procedure to calculate the quotient:You only calculate the next digit, multiply this digit number by the divisor and subtract this result. Add the next digit from above and repeat this process.Code:28.00000 ÷ 322 = 0.08695.... 0 ↓↓↓ 0 * 322 ---↓↓↓ 280↓↓ 0↓↓ 0 * 322 ----↓↓ 2800↓ 2576↓ 8 * 322 ----↓ 2240 1932 6 * 322 ----- 308
I hope this helps a little bit. Probably you'll find better explanations if you take a math book of the second class.
I figured it out...
::sigh::
I just did:
28.00 ÷ 322
Since I only needed the answer to the hundredth rounded, I finally figured it out. Yeah, I just need to see the work done to figure out how it's supposed to work and then from there I'll be able to apply that to future problems.
