How to separated Materials with an Object

Sorry for the confusing title, I’m trying to understand the basics of unity when it comes to the material side of things and I’m wanting to know how to replicate this object below with the materials being separated from one another at the front.


And at the back of the same object the object only uses one material instead200700-capture.png
I’ve looked around on google to see if there is any resources that could help me, but sadly my googling skills aren’t the best. So would anyone be able to point me in the direction of something that could help?

Cheers
