If it were 8.8/14.08 Then you would first move over one place from the 12.8. (Basically you would then have 88/140.8)
Now, you divide, 88 goes into 140 once, and your left with 52, bring down the 8, and 528. 88 goes into 528 six times evenly. Your left with 18, but the 140.8 has a decimal place one to the left, so you put your decimal place one to the left in your answer: 1.8
Yes
line up the decimals together
You need to line up decimals for additional and subtraction. For multiplication, you don't need to line them up - in fact, it would serve no useful purpose.
Yes. Line up them up when you're adding, too.
39.63 +42.35 ------------ 81.98 Just line up the decimals and then add.
Yes
line up the decimals together
Two ways: You can find a common denominator, convert them to equivalent fractions and line up the numerators or you can convert them to decimals by dividing the denominator into the numerator and line them up numerically. The second way is easier.

Just make sure you line up the decimals

If you are making use of long division method, the process of dividing a whole number is actually a subset of the process of dividing the decimals. While dividing both you may get a quotient with decimal places. Some exceptions to this do exist in case of whole numbers. Like when you are dividing 100 by 2, the quotient 50 has no decimal places.
in dividing decimals you never get a remainder and in dividing whole numbers you do. +++ More to the point perhaps, you are working in powers of 10 all the time.

By the time you advance to the point of dividing decimals, you don't use remainders any more.
