Looks like the "result" is in st1, and you store st0? Perhaps try "fdivp"?

Here, you seem to be storing the result in the same place 4 times.
Probably want "fst qword [esp]"/"fst qword [esp + 8]"/"fst qword [esp +
16]", etc. ???

I don't have a clue about GL, but those look "suspicious" to me... Hope
