Divide County ND begins in the NE corner of the county with Township 163N Range 95W. There is a "tiny" part of 164N, but it is very small (most of it lies outside the county to the north.) As you may know, a township is a six mile square area, and contains 36 one mile square sections within.
The townships get lower as you go straight south from the above location (i.e. 162N, 161N etc, and the furthest south in the county is 160N.
The ranges likewise have larger numbers as you move west. For example, the township and range directly east of 163N 95W is 163N 96W and so on as you go west, 97W, 98W etc. until at the westernmost part of the county you'll come to 103W. You might try drawing out a "grid" on some graph paper or a spreadsheet for a more visual representation of this.
Divide County is basically four townships "tall" and about nine townships "wide." Since each township consists of 6 square miles, Divide County is about 24 miles from north to south, and about 54 miles from east to west.
The tax assessor in Divide County would have records of who is paying the taxes on the surface currently. If you have the legal description (section, township, range and which "tract" or part of the section the subject land is located in) they may just tell you over the phone. I'm not sure if they're allowed to or not, but the assessor's office is who you could try first.
Another alternative would be to hire a "landman" to go look for you. The county clerk's office in Divide County could perhaps recommend one. There are plenty of landmen up there right now, but most are pretty busy. You might try the landman discussion forum on THIS web site also, as there may be someone on there who could help you.
Hope this helps you out.
