4 artilleries / division is arbitrary. It is derived from the fact that in clear terrain, in good weather, you will generally be able to commit 3 times more combat (inf, cav) units to combat than artillery units. So that is 12 inf(cav), 4 artillery units. You have filled almost entire division with it. You should not look at this composition as hard coded, you 'll be ok with 1-2 art more or less in the division as well.
Generally, it all depends on the terrain. In clear terrain you would want more, in rugged less artillery. And if you have good leader in Clear/Prairie/Desert/Wood areas, your engaged artillery numbers can skyrocket. Leader bonus to frontage is only applied in those relatively clear areas.
Here are some numbers:

So in Swamp, only 3 artilleries can fight at the same time, while in open terrain, with Grant (Rank = 3*; off = 6, Quota Mod = 3*6*10=180, (180+60)/4 = 60) on the offense 60 batteries can be present.
60 batteries = 60*12 = 720 guns. So if your opponent is Grant, and if he has so many guns, the only way to fight him is to dig behind large entrenchments or to take the battle in rugged terrains (as was the case historically - Wilderness battles for example).
I am posting an excell file ( [ATTACH]25345[/ATTACH] - credit to Major Tom) with all those numbers explained. You do not have to remember all those. It is enough to grasp that in rugged terrain most of your guns will be dead weight, while in open terrain you can never have enough of them.
