The problem is your heat full stop. What I would do is work out what is minimum, medium and high on your cooker/hob.
After that stick your pan on medium with some oil (tablespoon) and let it sit for 5 mins. The bottom line is that your pan will only get as hot as the hob and what you set it at. What type of pan are you using? A thin pan will not hold a heat not will it be even.
Additionally I would look at the thickness of your steak, if it is thin then there is no problem sticking the pan on a high heat and flash frying it. If it is a big thick fillet then your will burn the outside whilst not cooking the inside on a high heat.
In addition butter will burn, either quickly (stuck in a hot pan) or (slowly with some oil added), my advice is to cook the steak and clean the pan then add butter and baste or take the steak out and stick a knob of butter on it.
