Let's proceed to step 13:
The number 840 fits into 4400 5 times, leaving a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 66157.20595
If we take 4200 away from 4400, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 14:
If we divide 2000 by 840, we get 2 and a remainder of 320.
Use 2 as the next digit of our solution. 
Result so far: 66157.205952
Subtracting 1680 from 2000 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 15:
