Csplit is probably a good way to go, but here's another, which may chop off a
line before the nl, though.

: chunk - breakup a file into SIZE chunks called OUT01, OUT02, ...
[ !-r "$1" ] && echo "Usage: $0 inputfile [prefix [size]]"
IN=$1 
OUT=${2:-chunk}
SIZE=${3:-100000}
N=0
while :
do
	T=`expr $N + 1`
	[ $T -le 9 ] && T=0$T
	dd count=1  bs=$SIZE  if=$IN  skip=$N  of=$OUT$T
	[ ! -s $OUT$T ] && rm $OUT$T && break
	N=`expr $N + 1`
done
l $OUT* $IN
