Yes ,your approach is correct...

(s/k+1)steps up and down for s%k times and remaining steps were of length s/k.. 

Few corner cases would be if the maximum jump allowed is (s/k) then you can't jump the distance of(s/k+1)

if(s/k is zero) you would land in the same place at some time...(jump will have to be of zero size).
