Answer:
So you start off with 26 / 288; if you think of this as a fraction and just drop the numerator to the house you get the little division house we learned in school :
______
26 | 288 ; In this state it's easier to analyze by parts:
so, 26 goes into 28 once with a remainder of 2 -->
_1_____
26|288
-26↓
28
From this you see that it's exactly the same thing as the first step, so the answer would be approximately 11.2
