Write a(n)=[(bn+c)r]-b[nr]-[cr].  If r>0 and b and c are integers satisfying b>=2 and 0<=c<=b-1, then 0<=a(n)<=b.  The positions of 0 in the sequence a are of interest, as are the position sequences for 1,2,...,b.  These b+1 position sequences comprise a partition of the positive integers.
Examples:
(golden ratio,2,1):  A190427-A190430
(sqrt(2),2,0):  A190480-A190482
(sqrt(2),2,1):  A190483-A190486
(sqrt(2),3,0):  A190487-A190490
(sqrt(2),3,1):  A190491-A190495
(sqrt(2),3,2):  A190496-A190500
(sqrt(2),4,c):  A190544-A190566
