SQL Division returning odd value - sql

Question

So Basically I have two sum values, that I return. I then divide one of them by the other, my goal was to get spit out a basic value. However the Value that is returned is all over the place.
I assume I screwed up the "Cast" but I am not sure here.
It would be impossible for me to share the entirety of the SQL that generates this. I will focus on the end results here which start with an Outer Apply:
This is me calling the Outer apply values for display, and then my attempt at dividing them:
,VerifyBlock.Numa as [Numerator]
,VerifyBlock.Denominator
,(isNull(((VerifyBlock.Numa) / NullIF(VerifyBlock.Denominator,0)),0)) as [Division]
This is the outer apply that generates the above:
OUTER APPLY (SELECT CASE WHEN CAST(tmpdc2.[14]AS decimal(10,2)) <= 0 AND (CASE WHEN T4MathBlock.[Value] >0 THEN T4MathBlock.[Value]
ELSE '0.00' END)<= 0
THEN '0.00'
ELSE (CASE WHEN CAST(tmpdc2.[14]AS decimal(10,2)) < (CASE WHEN T4MathBlock.[Value] >0 THEN T4MathBlock.[Value]
ELSE '0.00' END) THEN CAST(tmpdc2.[14]AS decimal(10,2))
ELSE (CASE WHEN T4MathBlock.[Value] >0 THEN T4MathBlock.[Value]
ELSE '0.00' END) End)
END AS [Amount]
From ##TempDisclosure tmpdc2
WHERE tmpdc1.[Student Number] = Tmpdc2.[Student Number]
)[AF]
WHERE tmpdc1.[Student Number] = Tmpdc.[Student Number]
)[VerifyBlock]
Sorry if the formatting is wonky.
I know the Values generated by:
VerifyBlock.Numa and VerifyBlock.Denominator are solid. The values they return are
32747682.64 and 78740189.20 (Respectively)
The Division though returns: 947860.602435
When it should actually return: 0.4158954019886963
So where the heck did I go wrong here?
