80x86 Assembly Language div instruction integer overflow?

[CaptainJolly]

Hey guys, don't really post much on the forum(Or at all... ) but linus is our friend and his friends are my friends so friends help me if you may please.

 

Objective is to display the the result of a div instruction where the dividend is stored in register EAX. The problem I'm having is that the displayed result stored in EAX comes out wrong.

 

I have my .asm file in the link below I'd appreciate it if anyone could help me out.

Also we were supposed to display it onto a single window on two lines.

Objective:      Prompt and allocate DWORD(32 bits) size labels for Grade1-Grade4 and Weight1-Weight4.

                        Solve for WeightedSum = G1*W1 + G2*W2 + G3*W3 + G4*W4

                        Solve for SumOfWeights = W1 + W2 + W3 + W4

                        Solve for WeightedAverage = (WeightedSum/SumOfWeights)

                        Display WeightedAverage & WeightedSum

 

Grades:         Weights:

88              1

77              2

94              1

85              3

SumOfWeight = 7

WeightedSum = 591

WeightedAvg = 81        ;Displays 1792

 

 

And as always please and thank you!
