creating an average?

Hi all, I´m brand new here
I am building an excel worksheet that I input 4 different sets of data
Each set has its own page, and there are 12 pages for each month = 48 pages in total.
There is an additional page that totals all this information
Here i need to make an average of one of the sets of data which is the (TOTAL WIN) this average needs to be divided by how many days the data has been inputted for.
Here is the formula that i have so far - =SUMA(O7)/A7/THE AMOUNT OF DAYS???
Can any one tell me how this can be done?
Thanks

Why not use the AVERAGE function?
