While it's not a divider, it illustrates the principle that as long
as the voltages at NOM and DENOM are equal QUOT will always be equal
to 1V, even when NOM and DENOM are at 0V.
Except the positive feedback rails the output. So the circuit makes no
sense.
I don't need Spice to tell me that both opamps are always railed!
---
If you think they are, then you do.
---
Or what the voltage at QUOT will be if the obvious fixes were made; and
that won't be +1.
---
Obvious fixes? There are none as far as I can see, but if you have
some, be my guest.
In the meantime, chew on this:

That's crap, and it's a cheap shot.
You want everyone to believe that because you managed, somehow, to
make enough money to buy a fortune cookie factory that you can't be
wrong, technically, ever, in any way.
You're wrong, and if you've got the guts to admit it, you will.
Otherwise, you'll need to be beat into the ground, just like all of
the assholes that came before you.
