In future posts, please post the current version of your script along with any matching error messages.
You are quite a long way adrift with syntax. Note that when assigning variables there is no space character either side of the equals sign.
This should get you past the syntax errors.
Now! I wonder where the number 112000 came from? The units of the output from "du -s" are in "512 byte blocks".
Using the unix in-line calculator "bc" I get a different value for the number of 512 byte chunks in a Gigabyte.
The units of "du -sk" are easier to work with. See the "man" page for "du".

du
DU(1) BSD General Commands Manual DU(1)NAME
du -- display disk usage statistics
SYNOPSIS
du [-H | -L | -P] [-a | -d depth | -s] [-cghkmnrx] [file ...]
DESCRIPTION
The du utility displays the file system block usage for each file argument and for each directory in the file hierarchy rooted in each direc-
tory argument. If no file is specified, the block usage of the hierarchy rooted in the current directory is displayed.
The options are as follows:
-H Symbolic links on the command line are followed. (Symbolic links encountered in the tree traversal are not followed.)
-L All symbolic links are followed.
-P No symbolic links are followed.
-a Display an entry for each file in the file hierarchy.
-c Display the grand total after all the arguments have been processed.
-d Display an entry files and directories depth directories deep.
-g If the -g flag is specified, the number displayed is the number of gigabyte (1024*1024*1024 bytes) blocks.
-h If the -h flag is specified, the numbers will be displayed in "human-readable" format. Use unit suffixes: B (Byte), K (Kilobyte), M
(Megabyte), G (Gigabyte), T (Terabyte) and P (Petabyte).
-k By default, du displays the number of blocks as returned by the stat(2) system call, i.e. 512-byte blocks. If the -k flag is speci-
fied, the number displayed is the number of kilobyte (1024 bytes) blocks. Partial numbers of blocks are rounded up.
-m If the -m flag is specified, the number displayed is the number of megabyte (1024*1024 bytes) blocks.
-n Ignore files and directories with user "nodump" flag (UF_NODUMP) set.
-r Generate warning messages about directories that cannot be read. This is the default behaviour.
-s Display only the grand total for the specified files.
-x Filesystem mount points are not traversed.
du counts the storage used by symbolic links and not the files they reference unless the -H or -L option is specified. If either the -H or
-L options are specified, storage used by any symbolic links which are followed is not counted or displayed. The -H, -L and -P options over-
ride each other and the command's actions are determined by the last one specified.
Files having multiple hard links are counted (and displayed) a single time per du execution.
ENVIRONMENT
BLOCKSIZE If the environment variable BLOCKSIZE is set, and the -g, -h, -k, and -m options are not specified, the block counts will be dis-
played in units of that size block.
