Making istinja while fasting

Q: I recently learnt in my madresa that we should be careful when making ghusl in Ramadaan and that we should be careful when washing our behind because water gets sucked up and that will break the fast. My question is how should we wash the behind and till what extent, so that the water does not get sucked up.
