Your microflow should look something like this:
Use the list operation Subtract to remove the list DB_GroupDivision_Compare from the list DB_GroupDivision_1. You can delete the list that remains.
For the objects that need to be deleted, add them to a new list, and then delete these objects using the delete activity and point to this list.
Try this Intersect List Operation!
for finding data which is nor present in other list, use list operation (filter by expression) in that write a condition where $currentobject!=$listname. then use subtract activity to subtract the list which is not present.
