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.

audio::mpd::common::time
Audio::MPD::Common::Time(3pm) User Contributed Perl Documentation Audio::MPD::Common::Time(3pm)
NAME
Audio::MPD::Common::Time - class representing time of current song
VERSION
version 1.120881
DESCRIPTION
Audio::MPD::Common::Status returns some time information with the "time()" accessor. This information relates to the elapsed time of the
current song, as well as the remaining and total time. This information is encapsulated in an Audio::MPD::Common::Time object.
An Audio::MPD::Common::Time object does not update itself regularly, and thus should be used immediately.
Note: one should never ever instantiate an Audio::MPD::Common::Time object directly - use the mpd modules instead.
ATTRIBUTES
$time->time;
The time passed to the constructor, used to compute all others values (see methods). It is the time value (on the "time" line) of what the
MPD server returns to the status command. Defaults to "0:0".
METHODS
my $str = $time->sofar;
Return elapsed $time ("minutes:seconds" format).
my $str = $time->left;
Return remaining $time ("minutes:seconds" format).
my $str = $time->left;
Return total $time ("minutes:seconds" format).
my $percent = $time->percent;
Return elapsed $time (percentage, 1 digit).
my $secs = $time->seconds_sofar;
Return elapsed $time in seconds.
my $secs = $time->seconds_left;
Return remaining $time in seconds.
my $secs = $time->seconds_total;
Return total $time in seconds.
my $mins = $time->sofar_mins;
Return minutes part of elapsed $time.
my $secs = $time->sofar_secs;
Return seconds part of elapsed $time.
my $mins = $time->left_mins;
Return minutes part of remaining $time.
my $secs = $time->left_secs;
Return seconds part of remaining $time.
my $mins = $time->total_mins;
Return minutes part of total $time.
my $mins = $time->total_secs;
Return seconds part of total $time.
