Nikita,
First of all, congrats on becoming a CA!
Second, as pointed by Tushar there would be many documents listing the process flow
in statutory audit.
Third, I agree with Ravinder that a downloaded file would give you some comfort but
one should see the actual ledgers and supporting documents
to get a feel of the said process.
Lastly, consider joining a firm (as pointed by a member above) to get
hands-on-experience or join a practical training centre that would teach
this process by showing almost the simulated data.
Goodluck with your learning!
