troubles with error: Divide by zero error encountered - sql

Question

Hello two days I have tried to figure out why my code isn't working.
I am quite sure that it's a stupid mistake, but if anybody has time to check the code I would really appreciate.
I have tried to comment out this "SUM" case, but then everything else breaks
I know that this line screws with me, but I can't figure out how to fix this:
sum (Case when bm.CaseQTY IS NULL
then (k.postedqty / mm.CaseQTY)
else (k.postedqty / bm.CaseQTY)
End) as laoseiskaste,
sum (Case when bm.CaseQTY IS NULL
then ((k.postedqty-k.reservordered-k.reservphysical-k.picked+k.registered) / mm.CaseQTY)
else ((k.postedqty-k.reservordered-k.reservphysical-k.picked+k.registered) / bm.CaseQTY)
End) as vabakaste

In SSMS, hit Ctrl+F to open the Find & Replace dialogue box. Search the query for all instances of /. This will tell you everywhere that division is happening, plus some false positives.
In every single instance, the query is dividing by mm.CaseQTY or bm.CaseQTY. Those are the only two values, and the only two tables you have to worry about. One or the other of them is coming through as a zero.
We don't have access to your database, so we can't help you troubleshoot the data issue, but that's how I'd go about deciding where to start looking.
