Exclude variable data if not found

How do I write my controller code below so that if $find is not present in Other OE Referances (the Data in the table is a string), then exclude?

I get that I potentially need to run Other OE Referances through a loop to separate them, and then check, but I also have a feeling I am overthinking.

Controller Snippet:

$find = 'G060162A2';

$letsFind = DB::table('parts')
            ->where('OE Number', '=', $find)
            ->orWhere('Other OE Referances', '=', $find)
            ->get();

Database:

object(stdClass)#584 (4) {
  ["ID"]=>
  int(23)
  ["internal ID"]=>
  string(6) "160980"
  ["OE Number"]=>
  string(9) "G060162A2"
  ["Other OE Referances"]=>
  string(37) "83222152426 ,83222289720, 83222305397"
}
