Dominic McCarty, Table of n, a(n) for n = 1..10000

Formula

a(n) = round(n/sumdigit(n)) where "round" is the rounded integer part of the division and "sumdigit" is the sum of the digits of the number.

Example

a(15) = round(15/(1+5)) = round(2.5) = 3.
a(17) = round(17/(1+7)) = round(2.125) = 2.
a(62) = round(62/(6+2)) = round(7.75) = 8.
