one monitor to view excel and internet box

[CC]

How do I split a single monitor screen to view excel and another program at
the same time?

This sounds like a Windows question, rather than Excel.
To change the size of a window, if it's full screen, click the second box in
(to the left of the red X in the top right-hand corner), then you can grab
the corner & stretch or shrink to suit & you can grab the window & move it.

Resize the application windows of both so as to fit the screen width.
