The number 32 fits into 240 7 times, leaving a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 434.3437
Deduct 224 from 240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
160 divided by 32 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 434.34375
Subtracting 160 from 160 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
32 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 434.34375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
The number 32 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 434.34375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.
