Splitting Blog Pages --> 1,2,3 ...

I've been trying to figure out how to split my pages without having to manually split them and create multiple pages or sub-pages ... Some of my posts, being of a technical nature, are going to be "kind of long" and hand-crafting them each time would be a major pain.

I've seen it done, the end result, on various blog sites, I just haven't been able to figure out how to do it in Wordpress (I searched the forums there) or within Atahualpa (ditto on the forums). It might be because I'm asking the "search engine" the wrong question, but variations haven't helped.

I did find a link to a possible solution via Google by searching on "splitting blog pages" that makes sense -- http://rumahabi.com/split-wordpress-...o-2-pages.html -- but, before I start tweaking code I wanted to find out if there was already a built in way to do it (that I haven't found), or a better way to do it, or if the suggested solution is going to break something in Atahualpa 3.3.3. ???

Thanks in advance.
