Because it is a an arithmetic operation (you are trying to divide a number by 60)
Therefore you need an arithmetic expansion ( see:
Shell command language: arithmetic expansions )
so you can assign the result of the arithmetic expression to a variable (assignment means
variable=value)
If you do not do that, in your example
AnzahlUeberstunden=$AnzahlUeberstunden/60 what happens is that you assign the value of AnzahlUeberstunden concatenated with the text string
/60, so the result becomes
2040/60.

My second suggestion is called an arithmetic expression (which can be used in shells like ksh93, bash, zsh) in which variables can be modified without an explicit variable assignment.

acctcms
acctcms(1M) System Administration Commands acctcms(1M)
NAME
acctcms - command summary from process accounting records
SYNOPSIS
/usr/lib/acct/acctcms [-a [-o] [-p]] [-c] [-j] [-n] [-s]
[-t] filename...
DESCRIPTION
acctcms reads one or more filenames, normally in the form described in acct.h(3HEAD). It adds all records for processes that executed iden-
tically named commands, sorts them, and writes them to the standard output, normally using an internal summary format.
OPTIONS
-a Print output in ASCII rather than in the internal summary format. The output includes command name, number of times executed, total
kcore-minutes, total CPU minutes, total real minutes, mean size (in K), mean CPU minutes per invocation, "hog factor," characters
transferred, and blocks read and written, as in acctcom(1). Output is normally sorted by total kcore-minutes.
Use the following options only with the -a option:
-o Output a (non-prime) offshift-time-only command summary.
-p Output a prime-time-only command summary.
When -o and -p are used together, a combination prime-time and non-prime-time report is produced. All the output summaries are total
usage except number of times executed, CPU minutes, and real minutes, which are split into prime and non-prime.
-c Sort by total CPU time, rather than total kcore-minutes.
-j Combine all commands invoked only once under "***other".
-n Sort by number of command invocations.
-s Any file names encountered hereafter are already in internal summary format.
-t Process all records as total accounting records. The default internal summary format splits each field into prime and non-prime-time
parts. This option combines the prime and non-prime time parts into a single field that is the total of both, and provides upward
compatibility with old style acctcms internal summary format records.
EXAMPLES
Example 1 Using the acctcms command.
A typical sequence for performing daily command accounting and for maintaining a running total is:
example% acctcms filename ... > today
example% cp total previoustotal
example% acctcms -s today previoustotal > total
example% acctcms -a -s today

NOTES
Unpredictable output results if -t is used on new style internal summary format files, or if it is not used with old style internal summary
format files.
