In the 8 November 1910 election, the voters of Williams County voters determined that the county should be divided into a northern and a southern county. The vote was affirmative; the southern portion retained the Williams name; the newly created county was named "Divide", with Crosby as the seat. The county government was effected on 9 December of that year, and the county's boundaries have remained unchanged since that time. Most histories attribute the county name to its "division" from Williams County,  though the county's location on the Laurentian Divide, separating runoff waters between Hudson Bay and Gulf of Mexico, may have been involved. 
Divide County lies at the NW corner of North Dakota. Its northern boundary line abuts the south boundary line of Canada and its west boundary line abuts the east boundary line of the state of Montana. Its terrain consists of semi-arid rolling hills, dotted with lakes and ponds, partially devoted to agriculture.  The terrain generally slopes to the east; the northern part also slopes to the north while the southern part slopes to the south.  The county has a total area of 1,294 square miles (3,350 km2), of which 1,261 square miles (3,270 km2) is land and 33 square miles (85 km2) (2.6%) is water.
