We have exchange 2016 with five DBs. One db is getting bigger and bigger every day. Is there any way to find out the reason or fix this issue?

I have about 100 users and have available space on that DB. I even moved the mailbox from that DB.

DB won't shrink after mailbox move. You either need to move all mailboxes and remove this db. Or you can do offline defrag, which will shrink the db. Or leave db as it is and let Exchange manage it. I assume you are taking full db backup to purge the log files.
