I think the name of this and other similar sequences (A127032,
A127033, A127034, A127035, A127036, A127037, A127039) is confusing. It
has nothing to do with the division (but rather with taking a
logarithm), and it should be renamed to
"Maximal value of power m such that 3^m < n!"
with a formula
a(n) = floor( log(n!) / log(3) ).
