It's not really clear why you can't use the variable. The way it is now, I don't think it contains a useful value (what does the echo print for you?) but fixing the scripts so it works sounds like the best plan unless you can explain why it "simply doesn't work".
Assuming $x is the name of the file you are about to split, try something like this instead.
I put in the addition of one on the theory that this should do something vaguely useful even with files which are too small, with a slight bias towards making the last file in the series smaller than the others. (Maybe divide by 49 instead to compensate?)
I have been googling on the 'split' unix command to see if it can split a large file into 'n' number of files. Can anyone spare an example or a code snippet?
Thanks,

split
split(1) User Commands split(1)NAME
split - split a file into pieces
SYNOPSIS
split [-linecount | -l linecount] [-a suffixlength]
[file [name]]
split [-b n | nk | nm] [-a suffixlength] [file [name]]
DESCRIPTION
The split utility reads file and writes it in linecount-line pieces into a set of output-files. The name of the first output-file is name
with aa appended, and so on lexicographically, up to zz (a maximum of 676 files). The maximum length of name is 2 characters less than the
maximum filename length allowed by the filesystem. See statvfs(2). If no output name is given, x is used as the default (output-files will
be called xaa, xab, and so forth).
OPTIONS
The following options are supported:
-linecount | -l linecount
Number of lines in each piece. Defaults to 1000 lines.
-a suffixlength
Uses suffixlength letters to form the suffix portion of the filenames of the split file. If -a is not specified, the default suffix
length is 2. If the sum of the name operand and the suffixlength option-argument would create a filename exceeding NAME_MAX bytes, an
error will result; split will exit with a diagnostic message and no files will be created.
-b n
Splits a file into pieces n bytes in size.
-b nk
Splits a file into pieces n*1024 bytes in size.
-b nm
Splits a file into pieces n*1048576 bytes in size.
OPERANDS
The following operands are supported:
file The path name of the ordinary file to be split. If no input file is given or file is -, the standard input will be used.
name The prefix to be used for each of the files resulting from the split operation. If no name argument is given, x will be used as the
prefix of the output files. The combined length of the basename of prefix and suffixlength cannot exceed NAME_MAX bytes. See
OPTIONS.
USAGE
See largefile(5) for the description of the behavior of split when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of split: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
