Curve parameter often isn't the same thing as length...something about how nurbs are constructed, if I remember correctly. If you want to see the length of the curve at each division point you can use the Length Parameter component.  You can also select points at either relative or absolute lengths along a curve using the Evaluate Length component.

David is Correct.

I also don't know how to explain why, but here is an example:

Divide a 10" curve, and at first you might get parameters like: 0, 2.5, 5, 7.5, 10

Then scale the curve. and evaluate again. The parameter relationship is maintained, even if the length is completely different.
