Set it up:

6.85 divided by .5

Move the decimals to the right on both until you are dividing BY a whole number:

moving the decimal points over in the problem 6.85 divided by .5 turns the problem into 68.5 by 5

Now, go for it!

long division work for the problem 6.85 divided by .5...  So, 6.85 divided by .5 = 13.7
