Strange .csv format with double double quotes! Nevertheless, try this, which is working on your sample file and splitting by (around) 20 lines; adapt if it fulfills your request:
Code:
awk -F, 'NR==1          {hd=$0; fn=FILENAME "_" ++cnt}
         N && (T != $2) {fn=FILENAME "_" ++cnt; print hd > fn; N=0}
         !(NR%20)       {N=1}
                        {print > fn; T=$2}
        ' file

info

INFO(1) 							   User Commands							   INFO(1)

NAME

       info - read Info documents

SYNOPSIS

       info [OPTION]... [MENU-ITEM...]

DESCRIPTION

       Read documentation in Info format.

OPTIONS

       --apropos=STRING
	      look up STRING in all indices of all manuals.

       -d, --directory=DIR
	      add DIR to INFOPATH.

       --dribble=FILENAME
	      remember user keystrokes in FILENAME.

       -f, --file=FILENAME
	      specify Info file to visit.

       -h, --help
	      display this help and exit.

       --index-search=STRING
	      go to node pointed by index entry STRING.

       -n, --node=NODENAME
	      specify nodes in first visited Info file.

       -o, --output=FILENAME
	      output selected nodes to FILENAME.

       -R, --raw-escapes
	      output "raw" ANSI escapes (default).

       --no-raw-escapes
	      output escapes as literal text.

       --restore=FILENAME
	      read initial keystrokes from FILENAME.

       -O, --show-options, --usage
	      go to command-line options node.

       --subnodes
	      recursively output menu items.

       -w, --where, --location
	      print physical location of Info file.

       --vi-keys
	      use vi-like and less-like key bindings.

       --version
	      display version information and exit.

       The first non-option argument, if present, is the menu entry to start from; it is searched for in all `dir' files along INFOPATH.  If it is
       not present, info merges all `dir' files and shows the result.  Any remaining arguments are treated as the names of menu items relative	to
       the initial node visited.

EXAMPLES

       info   show top-level dir menu

       info emacs
	      start at emacs node from top-level dir

       info emacs buffers
	      start at buffers node within emacs manual

       info --show-options emacs
	      start at node with emacs' command line options

       info -f ./foo.info
	      show file ./foo.info, not searching dir
