We look at the division of 86814866 by 668 
We want to figure out the number of times 86814866 can be divided by 668.

Advancing to step 1:
668 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 668

Let's proceed to step 2:
86 divided by 668 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 668

Moving on to step 3:
868 divided by 668 is 1 with a remainder of 200.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 668 from 868 leaves us with 200.
Grab the next digit (1) from the dividend, add it to 200, then carry on: 2001 / 668

Moving on to step 4:
668 can be fit into 2001 2 times, resulting in a remainder of 665.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1336 from 2001 and we're left with 665.
Grab the next digit (4) from the dividend, add it to 665, then carry on: 6654 / 668

Step 5:
668 goes into 6654 9 times with a remainder of 642.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we subtract 6012 from 6654, we get 642.
Bring next digit (8) of the dividend behind the 642 and repeat the process: 6428 / 668

Going ahead to step 6:
If we divide 6428 by 668, we get 9 and a remainder of 416.
Use 9 as the next digit of our solution. 
Result so far: 1299.0
If we subtract 6012 from 6428, we get 416.
Fetch the next digit (6) from the dividend, attach it to 416 and continue: 4166 / 668

Advancing to step 7:
668 goes into 4166 6 times with a remainder of 158.
Put 6 as the next digit of the answer. 
Result so far: 12996.0
Subtracting 4008 from 4166 leaves us with 158.
Bring next digit (6) of the dividend behind the 158 and repeat the process: 1586 / 668

Going ahead to step 8:
If we divide 1586 by 668, we get 2 and a remainder of 250.
Write down 2 as next digit of the result. 
Result so far: 129962.0
If we take 1336 away from 1586, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 9:
If we divide 2500 by 668, we get 3 and a remainder of 496.
Use 3 as the next digit of our solution. 
Result so far: 129962.3
Subtracting 2004 from 2500 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 10:
If we divide 4960 by 668, we get 7 and a remainder of 284.
The number 7 becomes the next digit in our result. 
Result so far: 129962.37
Subtract 4676 from 4960 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 11:
2840 divided by 668 is 4 with a remainder of 168.
The next digit of our result is 4. 
Result so far: 129962.374
If we take 2672 away from 2840, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 12:
668 goes into 1680 2 times with a remainder of 344.
Record the quotient 2 as the next digit in the result. 
Result so far: 129962.3742
Subtract 1336 from 1680 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 13:
3440 divided by 668 is 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 129962.37425
Deduct 3340 from 3440 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 14:
The number 668 fits into 1000 1 times, leaving a remainder of 332.
The number 1 becomes the next digit in our result. 
Result so far: 129962.374251
If we subtract 668 from 1000, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 15:
When dividing 3320 by 668, we get 4 with a remainder of 648.
The next digit of our result is 4. 
Result so far: 129962.3742514
If we take 2672 away from 3320, we end up with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Going ahead to step 16:
668 goes into 6480 9 times with a remainder of 468.
Record the quotient 9 as the next digit in the result. 
Result so far: 129962.37425149
Subtracting 6012 from 6480 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

The final outcome is 129962.37425149, with a leftover of 4.68e-07.
