Is there a method to identify a numeric string within another numeric string and then express "duplicate"

As exmple data:

097102105111114100105112101108108101
could appear in another string

09710210511111410010511210110810810110010511410110 3105110097116111115111110105097

this would give me an indication that they could possibly be duplicates

all values are contained within same row, if duplicate appears then print "duplicate" in next column

Assuming A1 contains the first string and B1 contains the second string you could use:
=IF(FIND(A1,B1),"DUPLICATE","")
