So to find what goes into the first three squares underneath the 3, 07 you multiply 32 by 9 giving you 288
You then subtract this from 307 giving you 19, and then you bring the 2 down from above giving you 192. You now need to figure out how many times 32 can go into 192. 
The answer to this is 6 times. So you place the number 6 into the top box next to the 9 and multiply 32 by 6 giving you 192. 
You then put this into the boxes below 192 and subtract, giving you 0 in the last box below. 
 ____96
32/ 3, 072
 -288

 -192

Hope this helps!
