Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 107

On to step 2:
The number 107 fits into 68 0 times, leaving a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 107

Going ahead to step 3:
107 goes into 683 6 times with a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 642 from 683 leaves us with 41.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 107

Moving on to step 4:
The number 107 fits into 418 3 times, leaving a remainder of 97.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we subtract 321 from 418, we get 97.
Append the next digit (8) from the dividend to 97 and continue with: 978 / 107

On to step 5:
When dividing 978 by 107, we get 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 639.0
Deduct 963 from 978 and we're left with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 107

Moving on to step 6:
If we divide 155 by 107, we get 1 and a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 6391.0
Subtracting 107 from 155 leaves us with 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 107

On to step 7:
107 can be fit into 482 4 times, resulting in a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 63914.0
Subtract 428 from 482 to get 54.
Take the next digit (0) from the dividend and append it to 54, then repeat: 540 / 107

Moving on to step 8:
If we divide 540 by 107, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 639145.0
The remainder is 5 after subtracting 535 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
107 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 639145.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 107 fits into 500 4 times, leaving a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 639145.04
The remainder is 72 after subtracting 428 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
The number 107 fits into 720 6 times, leaving a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 639145.046
If we subtract 642 from 720, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 12:
When dividing 780 by 107, we get 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 639145.0467
Subtracting 749 from 780 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
If we divide 310 by 107, we get 2 and a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 639145.04672
Subtract 214 from 310 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 14:
960 divided by 107 is 8 with a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 639145.046728
If we take 856 away from 960, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 15:
107 goes into 1040 9 times with a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 639145.0467289
The remainder is 77 after subtracting 963 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 16:
If we divide 770 by 107, we get 7 and a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 639145.04672897
Subtracting 749 from 770 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 639145.04672897 and a remainder of 2.1e-08.
