	OFFSET	`0,3`
	EXAMPLE	`a(23)=115 since 115 is written in binary as 1110011 and 115/(1+1+1+0+0+1+1)=23 and there is no higher possibility (if k is more than 127 then k divided by its number of binary 1's is more than 26).`
	CROSSREFS	`A052489 is the base 10 equivalent. Cf. A000120, A049445, A058898, A065413, A065878, A065879.` `Sequence in context: A119018 A094748 A065879 this_sequence A090546 A059909 A007517` `Adjacent sequences: A065877 A065878 A065879 this_sequence A065881 A065882 A065883`
