Creating multi-page documents in InDesign involves several important steps. These include setting up a new document, establishing master pages, and managing page numbers and sections. Each step is essential for creating a well-organized and professional layout. To start, the user should open InDesign and create a new document.

Check the print dialog box "General" section. There's no way to just divide an InDesign document into peices, it splits when printing. If this fails, you could export your InDesign file to a PDF. Open a new InDesign document the size of the "pieces" you want, then place the PDF on multiple pages aligning them to the page edges where appropriate.

This could make selecting those pages to print rather cumbersome. The good news is that there is an option in the Print dialog box that is only activated if your document has multiple page sizes. This print option will select all the pages of the same size in the document and automatically generate a range of pages to print. Choose File > Print.

You can print only one spread per sheet. If the new page is larger than the currently selected paper size, InDesign prints as much as it can, but won’t automatically scale the page to fit the imageable area, unless you select Scale To Fit in the Setup area of the Print dialog box. You may also want to specify landscape orientation.
