Dividing is not working properly, according the way I think it should work.

Dividing is working now as well. The operating sequence was not clear to me. After seeing that on a Italian user video and copying this on my machine, the calculation blocked. The motor clutch was activated. Turn the machine off and manually turn the main shaft back, the mechanism game free again. Tried it a few times and the results were all correct. Please see the picture and the video on the 555555555 divided by 45 is 12345679.
