Open Up an Article
Go to Administrator >> Content >> Article Manager and open up any long article.
Put Your Cursor in the Text
Place your cursor in the text at the point where you want the pages to split.
Click Pagebreak
Scroll to the bottom of the page and click "Pagebreak".
Give the New Page a Title
Select a title for your new page and click "Insert Page Break". The second field called "Table of Contents Alias" will be the URL for this second page.
Repeat the Process
Keep clicking "Pagebreak" until you have split this article as many times as you wish. Each time you do, you should see a grey line across the page. When you're finished, click "Save".
Visit the Article
Now when you visit the article on the front of your site you should see two special items:
1) "Article Index" which serves as a table of contents to the article pages
2) Prev and Next buttons at the bottom of the article for people to move on to the next page
