Merged requested to merge fix/IO_CheckSteps=0 into master

The solution is to add an additional check to avoid division by zero.
Changelog is updated.
Contributed code is correctly formatted. (See the contributing guidelines).
License added to any new files.
No extraneous files have been added (e.g. compiler output or test data files).

master branch. To resolve these conflicts , see
