Going ahead to step 1:
668 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 668

Advancing to step 2:
668 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 668

668 goes into 865 1 times with a remainder of 197.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 197 after subtracting 668 from 865.
Take the next digit (4) from the dividend and append it to 197, then repeat: 1974 / 668

Moving on to step 4:
When dividing 1974 by 668, we get 2 with a remainder of 638.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1336 from 1974 to get 638.
Fetch the next digit (7) from the dividend, attach it to 638 and continue: 6387 / 668

Let's proceed to step 5:
When dividing 6387 by 668, we get 9 with a remainder of 375.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
The remainder is 375 after subtracting 6012 from 6387.
Take the next digit (4) from the dividend and append it to 375, then repeat: 3754 / 668

Advancing to step 6:
When dividing 3754 by 668, we get 5 with a remainder of 414.
The next digit of our result is 5. 
Result so far: 1295.0
Deduct 3340 from 3754 and we're left with 414.
Take the next digit (2) from the dividend and append it to 414, then repeat: 4142 / 668

Step 7:
When dividing 4142 by 668, we get 6 with a remainder of 134.
Write down 6 as next digit of the result. 
Result so far: 12956.0
Subtracting 4008 from 4142 leaves us with 134.
Grab the next digit (8) from the dividend, add it to 134, then carry on: 1348 / 668

Moving on to step 8:
668 can be fit into 1348 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 129562.0
Subtracting 1336 from 1348 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
668 can be fit into 120 0 times, resulting in a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 129562.0
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
If we divide 1200 by 668, we get 1 and a remainder of 532.
Record the quotient 1 as the next digit in the result. 
Result so far: 129562.01
Subtract 668 from 1200 to get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Let's proceed to step 11:
If we divide 5320 by 668, we get 7 and a remainder of 644.
Record the quotient 7 as the next digit in the result. 
Result so far: 129562.017
Subtracting 4676 from 5320 leaves us with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Moving on to step 12:
When dividing 6440 by 668, we get 9 with a remainder of 428.
Record the quotient 9 as the next digit in the result. 
Result so far: 129562.0179
The remainder is 428 after subtracting 6012 from 6440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 13:
When dividing 4280 by 668, we get 6 with a remainder of 272.
Record the quotient 6 as the next digit in the result. 
Result so far: 129562.01796
Subtract 4008 from 4280 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 14:
668 goes into 2720 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 129562.017964
If we take 2672 away from 2720, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 15:
668 can be fit into 480 0 times, resulting in a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 129562.017964
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 16:
The number 668 fits into 4800 7 times, leaving a remainder of 124.
The next digit of our result is 7. 
Result so far: 129562.01796407
If we subtract 4676 from 4800, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

After the division, we end up with 129562.01796407 and a remainder of 1.24e-07.
