Use WordPress within a div

I have been searching for hours now. I do apologize if I am asking a redundant question.

I currently have a network of static html pages wherein I have left space to add a WordPress component that would integrate a blog into the front page and a few other pages of my site. I want to use WordPress as a CMS.

What I would like to do is grant WordPress access to a div and contain my blog within my static page. It seems this not possible based on my research.

I could convert all my pages to WordPress themes but I would rather not. Any suggestions for workarounds?

Thank you very much.
