How can I delete several pages of text from my Google Docs document?

I have a Google Docs file that contains about 250 pages of text. Only pages 180-230 apply to me, so I wanted to delete the unnecessary pages from the document.

I have tried to drag my cursor over the text, but of course, this is very unpractical as there are hundreds of pages I would have to drag my cursor over.

So, is there any way for me to select the text on select pages in the document and then delete it?
