Advancing to step 11:
The number 73 fits into 260 3 times, leaving a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 9409.64383
Deduct 219 from 260 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 12:
