[DICT] ArithmeticException divided by zero when showing JobStatus

[kharalast5]

If an incorrect config file is uploaded and run its job, there seems to be an Exception when showing JobStatus.

It seems to be an ArithmeticException divided by zero.

We will need to fix it.

The below is the stacktrace.

! @746mkk0g3 - Internal server error, for (GET) [/job/status?order=asc&limit=10&
offset=0] ->
