Take a single cell and divide it into rows

Hi Everyone!

I am new here and need some help. I have Microsoft Excel 2003, not all that experience and have never used Macros. I am designing a database for my uncle and have reached a problem. Currently my data looks like this:

Column A1 is business name and is fine
Column B1, and C1 is city and address which are also fine
Columns D1, E1, F1, and G1 is where my problem arises. Each of these columns will need multiple lines of data in them. D1 is contacts (and for some companies I have 10+ contacts) E1 is contact title (need this to line up with D1), F1 is contact email and G1 is contact phone number. I need all of these to line up. Currently I just have them on separate lines, but some do not line up. How can I divide these cells into separate rows (not columns) so they have lines and are easy to read and follow? Any help would be much appreciated!! Thanks in advance.
