Hi there,
One thing that would help you a lot i think is to do a simulation point for pin 2 and another for pin 3 of the second op amp shown in your schematic. That would tell you the voltages there and help to understand what exactly is happening here. The input offset voltage appears to be the cause of the 0.7v output, and doing the calculations it works out to a typical value for this type of op amp so i would believe that is what is happening here.
Once you assume the 0.7v output, you can use a simple resistive divider formula to get the answer to the input pin 2. The formula is:
V2=V1*R2/(R1+R2)
or in this case:
Vpin2=Vout*R9/(R9+R10)
