Moving on to step 9:
The number 455 fits into 2170 4 times, leaving a remainder of 350.
Write down 4 as next digit of the result. 
Result so far: 47227.4
If we subtract 1820 from 2170, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 10:
3500 divided by 455 is 7 with a remainder of 315.
Use 7 as the next digit of our solution. 
Result so far: 47227.47
Subtracting 3185 from 3500 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 11:
3150 divided by 455 is 6 with a remainder of 420.
Write down 6 as next digit of the result. 
Result so far: 47227.476
The remainder is 420 after subtracting 2730 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 12:
455 goes into 4200 9 times with a remainder of 105.
The next digit of our result is 9. 
Result so far: 47227.4769
Subtract 4095 from 4200 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 13:
455 goes into 1050 2 times with a remainder of 140.
Use 2 as the next digit of our solution. 
Result so far: 47227.47692
Deduct 910 from 1050 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 14:
If we divide 1400 by 455, we get 3 and a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 47227.476923
If we take 1365 away from 1400, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 15:
When dividing 350 by 455, we get 0 with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 47227.476923
