When you divide into a decimal, just ignore the decimal point doing your work at the bottom. If you run out of decimal places, just add a 0 to the end.

5 doesn't go into 2, so skip to the next part.
5 goes into 24 a total of 4 times.
4 times 5 is 20. 24 minus 20 is 4. Bring down the 5.
5 goes into 45 a total of 9 times.
9 times 5 is 45. 45 minus 45 is 0. Bring down the 3.
Bring up the decimal point.
5 doesn't go into 3, so put up a 0.
0 times 5 is 0. 3 minus 0 is 3. Add a zero to the end and bring it down.
5 goes into 30 a total of 6 times.
6 times 5 is 30. 30 minus 30 is 0. We're done!

Your answer is 49.06.
