Determining Ownership Percentage

I have a copy of a well permit in Marshall Co, WV that shows each RO of the parcel that is included in the permit of which we have an interest. How do we determine the percentage of ownership that is ours for that parcel? It is a 102 acres parcel and our share is 24.0834 net acres. Do you simply divide the net acres by the total or divide the total number of other RO’s into the total acreage? Probably a dumb question for one of you professionals. Trying to be prepared when an eventual Division Order arrives later this year. Thanks
