Default Templates

I am a bit confused on the default templates available. I understand the basis of landscape and portrait, so on and so forth. The only thing I am trying to figure out is what is the difference between the following: Letter Landscape div10, Letter Landscape div4, Letter Landscape div8?

Can anyone explain this to me?

Thanks!

If you choose to use a grid paper…
div 10 would indicate the Major Grid is subdivided by a Minor Grid of ten

That is great I will have to play around with it a bit. Thank you so much!
