its very easy,first turn off the power,remove all the trays from inside oven,at thevrear of the oven there is a metal plate,this is norm held on by two or four screws,remove them,and lift the plate off,you will now be looking at the element(its the round unit)
now if your lucks in,you may have the type that is held inplace by 2 screws,if so remove them and also the 2or3 screws holding the element to the casing,withdraw the element slowly till you can see the cable terminals,(they are very short)take note of the connections,then get your self a new element,and reasemble,if you have the type thats held in with nuts,then you will have to remove the rear panel of the oven to remove the nuts.
