How to output user guide sections as separate webpages?

I have a massive user guide (MS Word file) that has various sections and sub-sections (e.g., 1.2, 1.2.3, etc.). When I output using Webhelp, Responsive HTML5, or any other SSL, the guide is published as one long webpage. I can use the TOC to navigate to selected sections, but I can of course scroll up or down to other sections. Is there a way to isolate and output each section as a separate page, while keeping the comprehensive TOC?

It would be incredibly time-consuming to divide up the actual Word file...then import them individually into Robohelp...

I'm very new to Robohelp, so any help is much appreciated! Thanks!
