If I write:

N[4209/0.14,100] I get:
30064.3

But if I write N[420900/14,100] I get:
30064.285714285714285714285714285714285714285714285714285714285714285714
285714\
28571428571428571428571

Why the difference? I thought N determined the number of digitals shown
- but I seem to have some problems with this function. And it is not in
this example only.
