A family of Microsoft word processing software products for creating web, email, and print documents.
As mentioned previously, Word is not the best application for your requirements; Publisher, PowerPoint or any other graphic application would do better.
But saying that, if you must use Word, then create it as you need, then convert to a PDF. Then using Acrobat itself you do get the option to Print to "Tile Large Pages" which will give you options to split the one page across many pages.
There are other PDF creating software not just Adobe (some are free) but I do not know if they also have this facility.
Hope this helps
