%e There is 1 terms of A114440 that requires no steps to reach 1: {1}. So a(0) = 1.

%e There are 8 terms of A114440 that require one step to reach 1: {2,3,4,5,6,7,8,9}. So a(1) = 8.

%e There are 14 terms of A114440 that require two steps to reach 1: {12,18,21,24,27,36,42,45,48,54,63,72,81,84}. So a(2) = 14.

%e ...

%e There are 4 terms of A114440 that require 440 steps to reach 1, so a(440) = 4. There are no terms that require more than 440 steps to reach 1.

%Y Cf. A114440, A235601.
