I read that you can compare the background blurriness by dividing the focal length and the aperture.

It's a bit more complicated than that. Which of the two will give more background blur depends on the magnification as well as the distance between the subject and the background.

There is also the look of the OOF areas, which is what traditionally has been called "bokeh", and that also depends on the spherical aberration corrections. You can have more blur with hard outlines, or less blur with very soft edges, and it's difficult to tell without testing which case you will like better.

I too prefer to reserve the word "bokeh" for the quality rather than quantity of the blur. They are of course two completely different things. The quantity is something you can deduce from the lens specs and the shooting situation. For the quality, you have to look at how the lens actually performs.
