We're dividing 83686454 by 667 
Our goal is to divide 83686454 by 667.

Moving on to step 1:
The number 667 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 667

On to step 2:
If we divide 83 by 667, we get 0 and a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Include the next digit (6) from the dividend after 83, then repeat: 836 / 667

Step 3:
667 goes into 836 1 times with a remainder of 169.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 667 away from 836, we end up with 169.
Grab the next digit (8) from the dividend, add it to 169, then carry on: 1698 / 667

Moving on to step 4:
667 can be fit into 1698 2 times, resulting in a remainder of 364.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1334 from 1698 leaves us with 364.
Include the next digit (6) from the dividend after 364, then repeat: 3646 / 667

Moving on to step 5:
3646 divided by 667 is 5 with a remainder of 311.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Deduct 3335 from 3646 and we're left with 311.
Include the next digit (4) from the dividend after 311, then repeat: 3114 / 667

Advancing to step 6:
When dividing 3114 by 667, we get 4 with a remainder of 446.
The next digit of our result is 4. 
Result so far: 1254.0
If we subtract 2668 from 3114, we get 446.
Append the next digit (5) from the dividend to 446 and continue with: 4465 / 667

Moving on to step 7:
667 can be fit into 4465 6 times, resulting in a remainder of 463.
Write down 6 as next digit of the result. 
Result so far: 12546.0
The remainder is 463 after subtracting 4002 from 4465.
Include the next digit (4) from the dividend after 463, then repeat: 4634 / 667

Advancing to step 8:
667 can be fit into 4634 6 times, resulting in a remainder of 632.
Write down 6 as next digit of the result. 
Result so far: 125466.0
Deduct 4002 from 4634 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Step 9:
6320 divided by 667 is 9 with a remainder of 317.
The next digit of our result is 9. 
Result so far: 125466.9
The remainder is 317 after subtracting 6003 from 6320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 10:
667 can be fit into 3170 4 times, resulting in a remainder of 502.
Put 4 as the next digit of the answer. 
Result so far: 125466.94
If we subtract 2668 from 3170, we get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Let's proceed to step 11:
667 goes into 5020 7 times with a remainder of 351.
Put 7 as the next digit of the answer. 
Result so far: 125466.947
If we subtract 4669 from 5020, we get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 12:
The number 667 fits into 3510 5 times, leaving a remainder of 175.
The next digit of our result is 5. 
Result so far: 125466.9475
Subtract 3335 from 3510 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 13:
667 goes into 1750 2 times with a remainder of 416.
Record the quotient 2 as the next digit in the result. 
Result so far: 125466.94752
If we take 1334 away from 1750, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 14:
The number 667 fits into 4160 6 times, leaving a remainder of 158.
Put 6 as the next digit of the answer. 
Result so far: 125466.947526
If we subtract 4002 from 4160, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 15:
If we divide 1580 by 667, we get 2 and a remainder of 246.
Use 2 as the next digit of our solution. 
Result so far: 125466.9475262
The remainder is 246 after subtracting 1334 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 16:
667 can be fit into 2460 3 times, resulting in a remainder of 459.
Record the quotient 3 as the next digit in the result. 
Result so far: 125466.94752623
Deduct 2001 from 2460 and we're left with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

The final outcome is 125466.94752623, with a leftover of 4.59e-07.
