The last row has one digit. If this digit divides the top row integer, we have a hit. No hit here for 2015 (as 2 doesn't divide 2015) and no hit for 2216 (as 3 doesn't divide 2216), but two hits for 2014 and 2016. No division by zero is accepted. Leading zeros below the first row must be kept if they arise. LINKS CROSSREFS This is not A048378.
