I think what you want is to create Data Driven Pages.
Is not hard so this might be enough.
Once you read the link the question is how to "make" the different windows. As far as I Know there are 2 easy ways:
First, create a polygon shapefile, draw a rectangle and do it the shape and size you want for the "windows" copy and paste this one as many times as you need and use this as the frame of your future driven pages.
Second, you can use Strip Map Index which, basically, creates the "windows" automatically by following a feature (a line.. polygons..) but I'm not gonna get into this one because creating the frames with rectangles is much easier and will fit better for your area.
I hope this helps, if not, let me know and I'll explain how data driven pages works better.
