I always use the geometry calculator. This way I do not have to waste time changing my pdmode and pdsize every time I need something divided.
Additionally, the measure and divide commands are practically useless when setting up window mullions or other objects that are center-to-center with equal spaces between.
I would typically only use Measure and Divide on curved objects.
First ENTER> Offset (usually my original command)
...you are prompted for a distance...
at command prompt >>>>Expression: ENTER> dist(int,int)/number of spaces you want.
The formula is always the same and the only thing that changes is the number of spaces you want.
You can use any snap modes in the brackets (nea,per) would also be very common. When you get good at this you will easily surpass anyone using the Divide and Measure commands.
