Here "n" - number of users. In case the line count of infile is not exactly divisible by the number of users, then it ll create a new file with the remainder lines.
Try this ..
Code:
$ wc -l infile | nawk -v n=3 '{print "expr "$1" / "n"|bc" }' | sh | sed 's,^,split -,g;s,$, infile,g' | sh

splitshp

splitshp(1)						      General Commands Manual						       splitshp(1)

NAME

       splitshp - Split Shape into frames or combine frames into Shapes

SYNOPSIS

       splitshp SHAPE FRAME...

       splitshp SHAPE

DESCRIPTION

       Shape  files are used for storage of all visible elements (from UI buttons to terrain features) of the games Exult supports. Shapes contain
       one or more frames.  splitshp can be used to combine frames into one file, or split a Shape file into its component frames.

       The mode of operation is determined by looking at the number of commandline arguments. Exactly one argument means splitting, more than  one
       argument signals a combining operation.

   Combining
       Each  FRAME  names a Shape file typically consisting of only one frame (i.e.  subsequent frames are ignored). All these frames are concate-
       nated and written to the Shape file SHAPE.

   Splitting
       SHAPE will be read and split into its component frames. Each of those will be written to its own Shape file. The names of these	files  are
       determined by splitting the name of SHAPE before the last dot -- anything before this dot is the STEM, anything else (including the dot) is
       the PREFIX, which may be empty in case there is no dot in the name. The output files are then named STEM_nnSUFFIX with nn replaced  by  the
       frame number.

EXAMPLES

       splitshp button.shp button-up.shp button-down.shp
	      Packs the (first) two frames from button-up.shp and button-down.shp into the Shape file button.shp

       splitshp grizzly
	      Unpacks the frames contained in the Shape file grizzly into the (single-frame) Shape files grizzly_00, grizzly_01, grizzly_02, etc.

       splitshp boar.new.shp
	      Unpacks  the  frames  contained in the Shape file boar.new.shp into the (single-frame) Shape files boar.new_00.shp, boar.new_01.shp,
	      boar.new_02.shp, etc.
