John meant to divide a number by $2$, but he was careless and subtracted $2$ from the number instead.  He got an answer of $22$.  What would his answer have been had he actually divided by $2$ instead of subtracting $2$?
Please reason step by step, and put your final answer within \boxed{{}}.<|im_end|>
