You've already got the right idea of it in that 125 PDef cuts damage roughly in half. That formula you have is the base damage, and then the defense formula that I posted reduces the damage according to the physical defense of the target. In that example where you have the base damage value of 879, if an enemy hits a target with 190 PDef, it will deal 65/255 damage, or about 224.
