'-type f' means "only look for regular files". Other options might be 'd' for directories, 'l' for links, ...
The '+5M' doesn't work because it's apparently only implemented in GNU find. Sorry for that.
The awk line uses the 5th field of the output from 'ls -l' (which is the size) and prints it divided by 2.
-b tells split to split after that many bytes (from the awk above). The 2 others are the file itself that needs splitting and the prefix for the new name (sadly, requires full path).

SPLIT(1) General Commands Manual SPLIT(1)
NAME
split - split a file into pieces
SYNOPSIS
split [ option ... ] [ file ]
DESCRIPTION
Split reads file (standard input by default) and writes it in pieces of 1000 lines per output file. The names of the output files are xaa,
xab, and so on to xzz. The options are
-n Split into n-line pieces.
-e expression
File divisions occur at each line that matches a regular expression; see regexp(6). Multiple -e options may appear. If a subex-
pression of expression is contained in parentheses (...), the output file name is the portion of the line which matches the subex-
pression.
-f stem
Use stem instead of x in output file names.
-s suffix
Append suffix to names identified under -e.
-x Exclude the matched input line from the output file.
-i Ignore case in option -e; force output file names (excluding the suffix) to lower case.
