Moving on to step 8:
173 goes into 1381 7 times with a remainder of 170.
Write down 7 as next digit of the result. 
Result so far: 212077.0
If we take 1211 away from 1381, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 9:
If we divide 1700 by 173, we get 9 and a remainder of 143.
Put 9 as the next digit of the answer. 
Result so far: 212077.9
The remainder is 143 after subtracting 1557 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 10:
1430 divided by 173 is 8 with a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 212077.98
Deduct 1384 from 1430 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
173 goes into 460 2 times with a remainder of 114.
The next digit of our result is 2. 
Result so far: 212077.982
If we take 346 away from 460, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 12:
173 goes into 1140 6 times with a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 212077.9826
Subtract 1038 from 1140 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 13:
173 goes into 1020 5 times with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 212077.98265
If we take 865 away from 1020, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 14:
173 can be fit into 1550 8 times, resulting in a remainder of 166.
Put 8 as the next digit of the answer. 
Result so far: 212077.982658
The remainder is 166 after subtracting 1384 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 15:
1660 divided by 173 is 9 with a remainder of 103.
Put 9 as the next digit of the answer. 
Result so far: 212077.9826589
Deduct 1557 from 1660 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 16:
When dividing 1030 by 173, we get 5 with a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 212077.98265895
Subtract 865 from 1030 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The final result is 212077.98265895 with a remainder of 1.65e-07.
