well for any fixed number you can ensure that the document you use for
the iteration (which doesn't have to be your source document) has
enough nodes: for example you can use the stylesheet
document('')//node()
and have as many nodes as you want in that (add 1000 empty comments at
the end if need be)
if you are picking up a number dynamically it's probably easier to just
give in and write the recursive template (which after all is only 4 or 5
lines of code) apart from anything else loading a massive document just
tp iterate overthe integers is a bit expensive.
But if you really want to use //node() then
z=document('')//node())
m=count($z)
a=floor($n div $m)
b=$n - $a*$m
for-each $z[position() <= $a]
  for-each $z
for-each $z[position() <= $b]

will do any number of iterations up to the square of the number of nodes
in the stylesheet which can be a pretty big number.
(I may have got the sums wrong but too late to think about that too
hard)
