| I don't know how to justify this usage of the zero article to non-native speakers. |

I don't think I have an answer which applies in general to all such
usage. In the case at hand, however, maybe the following helps a
little.
When we use "the registration", we present the description "the
registration" expecting the listener to be able to pick out its
referent in the real world, possibly because we have spoken of this
very process of registration previously. We are saying that the
aforementioned registration of the company took place yesterday.
When we use simply "registration", we don't expect the listener to be
able to pick out its referent in the real world. We expect less
of the listener. The listener may even ask "What registration are
you talking about?" or "What is a registration?" or "What does that
mean?" Perhaps this version leans more toward saying "A certain
process called 'registration of the company' took place yesterday."
I admit it's not a strong argument, but it may have a kernel of something you can develop out of it on your own.
