[4.x]: DivisionByZeroError in UpdateElementSlugsAndUris job

[joostwaaijer]

What happened?

Description

We are experiencing an issue in one of our site where the UpdateElementSlugsAndUris is reporting a DivisionByZeroError. The issue is happening on this line:
$this->setProgress($queue, $this->_totalProcessed++ / $this->_totalToProcess);

Looks like $this->_totalToProcess can sometimes be 0 while in the foreach (Db::each($query) as $element) { loop

Steps to reproduce

1. Run the UpdateElementSlugsAndUris job
2. Randomly it can crash by a DivisionByZeroError
