Maintain table with too many insert
There isn't any way to reset autoincrement such that it goes back to the beginning and just overwrites existing data.  Autoincrement isn't built that way.

What you could do is update rather than insert.  You'd have to either pre-populate every record with blank data so that every entry is always an update, or you could write a procedure which tries to read the next ID first and then either inserts or updates accordingly.  Either way, you will need to track the next ID yourself instead of letting the database handle it for you (with autoincrement).  When you get to the maximum value, reset the next ID to 1 and keep going.

Thinking Practically:

The largest value for UNSIGNED BIGINT is 18,446,744,073,709,551,615.  Depending on what is in your record you are looking at thousands (even millions) of petabytes of data.  Are you sure you aren't going to have space constraints with that much data?  You may find that what you need to do is purge out data that is old enough to be discarded as you go just to make room in your database.  If you do that, then you can avoid the prepopulation and just insert every time.  

If you purge periodically, say every night, then you just need to wait until the gap between where your remaining data is and ID=1 is big enough that you don't have to worry about ID collisions.  When that happens, reseed your ID and start inserting from ID=1 again.  If you do this, then you can go back to using autoincrement.

Edit: Additional Information about reseeding...

OP mentioned in a comment that the command for reseeding an autoincrement column in mysql is of interest.  This command will reset the starting autoincrement value:

ALTER TABLE table AUTO_INCREMENT = 1


I have read that this should be done with caution because it can take a long time in a large table.

See also the documentation for AUTO_INCREMENT.
