How to take information from one Cell based on another cells information from the same row

I have a problem that I don't know the answear to.
In Column A I have a list of diffrent names (sometimes the same name are repeating) and in Column H I have a bunch of numbers that are specific to the names of the column A. What I need to do is take every instance of the number in the Column H that Shares the same name in the Column A and then divide it by the ammount of times that this Column's name has been repeated. What Formula would be used for something like this? I tried to search online but I wasn't lucky with it.

Thank you for your time!

So I assume I was vague in my initial post, I know how to calculate avrage of the numbers, What I'm haveing a problem is how to a get a number from one cell based on the information from a diffrent cell in the same row? Like I'm not sure how to get these numbers from the spreadsheet to begin with. I made a quick example of what I mean. Basically What I'm asking is how I would take every value that is corresponding with M for example.1123.jpg

=averageif(e5:e110,"m",f5:f110)

That works Thank You !
