If I cut through an object in the middle and then put the other half back on, there is a small line in the middle that can be seen at different zoom levels. How can I avoid this? I work without a contour.
sorry, all i have is a noob answer for you, i'm not sure what else it might be. Do you have your stroke set to no color? shift left click the X on the left side of swatches to set null. or set stroke to x in fill and stroke menu.
If you don't want to have a visible division, why do you need to divide the circle into separate objects?
But - while waiting for the answer - I give you one solution, I know of. If you take Marcos advice, the effect should be minimized. Still it may be visible. I suppose this is because of floating point operations.
What I would do is duplicate the right half of the circle. Then zoom in, select the duplicate and move it to the left using ALT+LEFT-ARROW. Now select the duplicate and the original right half of the circle. Press CTRL+PLUS to unify those objects. Now you have two slightly overlapping half circles and your problem should be gone. (Keyboard-Shortcuts may differ, as I use the german version.)

After performing a division using a stroke with thickness 0 or "none", be sure the stroke you use is perfectly perpendicular to minimize this effect.

Look at my example.
