I divided an arc by length and used the first cut to generate a subCurve. Somewhere on this way the operation became very unprecise. (is: 51.6 mm, should be:50mm)
Rebuiding the arc to a curve won´t fix it.
Am I missing something?

Correct, because DivideByDistance measures the distance between points. A detailed explanation is provide here for your reference.
