Hello,
according to the following three Wiki Entries the X and Y values used for p (put) and g (get) commands are popped the other way around from the stack.

• https://esolangs.org/wiki/Befunge
• https://de.wikipedia.org/wiki/Befunge
• https://en.wikipedia.org/wiki/Befunge

According tho those wikies, the first poped value is Y and the second one is X (and the third one is V) but in your visual-befunge93-interpreter they are used as if the first value is X and the second one is Y this causes you to have to enter them in reversed order and also makes a lot of befunge examples not work correctly.

Your links inside the README.md file are deprecated. I created a patch for you which should update all links:

i know its kindof wierd to divide with an empty stack, but what the compiler does should not be happening at all, if you input the code

/@

it will put NaN in the stack 🤔
i'd suggest either printing some sort of error and not putting anything in the stack

what you are currently doing in your code is dividing 0/0 (scince befunge defaults a empty stack to 0) and 0/0 is not possible
