Is it possible to use a 'Next Page' attribute in Posts?

With my current knowledge on WordPress, it would appear i’m asking too much of a blogging website, as I’m fully aware it is not a CMS and doesn’t use ‘pages’.

However, I’m wondering if it is possible to split a post into essentially 2 posts, at the bottom of one, having a ‘next page’ link to go to the rest of it like they do on many websites.

I can’t think of any possible way to do this atm, as a post is a post and NOT a page, it’s completely dynamic.

I don’t really want a mile long page on my website on one part of a huge topic, it looks silly and unprofessional.

I don’t have time at the moment to start changing my theme to allow for a full width template – There seems to be a lack of themes which are. My content is kind of squashed up on one page which makes it very long.

I may have to leave wordpress and use a CMS, not what I want to do 🙁
Thanks for your help!
