I would have the student review 8×9 and 9×8 just to ensure that they realize that each problem has the same answer.
Next, student 2 has issues bringing down the proper numbers upon the first round of subtraction. This clearly is a result of misplacement. Placement is crucial in long division because if the student places the quotient in the wrong place, the entire problem is ruined! The third student has misplaced the quotient from the start and thus ruined his chances for a correct answer. This student too needs assistance in placement. He does, however have the mechanics in hand thus is in better shape than the second student.
