We look at the division of 83557394 by 668 
We want to figure out the number of times 83557394 can be divided by 668.

On to step 1:
668 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 668

Going ahead to step 2:
When dividing 83 by 668, we get 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Grab the next digit (5) from the dividend, add it to 83, then carry on: 835 / 668

Moving on to step 3:
The number 668 fits into 835 1 times, leaving a remainder of 167.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 668 from 835 to get 167.
Append the next digit (5) from the dividend to 167 and continue with: 1675 / 668

Advancing to step 4:
If we divide 1675 by 668, we get 2 and a remainder of 339.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1336 from 1675 to get 339.
Append the next digit (7) from the dividend to 339 and continue with: 3397 / 668

On to step 5:
668 can be fit into 3397 5 times, resulting in a remainder of 57.
Write down 5 as next digit of the result. 
Result so far: 125.0
Subtracting 3340 from 3397 leaves us with 57.
Fetch the next digit (3) from the dividend, attach it to 57 and continue: 573 / 668

Moving on to step 6:
The number 668 fits into 573 0 times, leaving a remainder of 573.
The next digit of our result is 0. 
Result so far: 1250.0
Subtracting 0 from 573 leaves us with 573.
Bring next digit (9) of the dividend behind the 573 and repeat the process: 5739 / 668

Going ahead to step 7:
5739 divided by 668 is 8 with a remainder of 395.
The next digit of our result is 8. 
Result so far: 12508.0
The remainder is 395 after subtracting 5344 from 5739.
Append the next digit (4) from the dividend to 395 and continue with: 3954 / 668

Going ahead to step 8:
668 can be fit into 3954 5 times, resulting in a remainder of 614.
The next digit of our result is 5. 
Result so far: 125085.0
If we take 3340 away from 3954, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Moving on to step 9:
668 goes into 6140 9 times with a remainder of 128.
Use 9 as the next digit of our solution. 
Result so far: 125085.9
Deduct 6012 from 6140 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 10:
If we divide 1280 by 668, we get 1 and a remainder of 612.
Use 1 as the next digit of our solution. 
Result so far: 125085.91
Subtract 668 from 1280 to get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Let's proceed to step 11:
6120 divided by 668 is 9 with a remainder of 108.
Put 9 as the next digit of the answer. 
Result so far: 125085.919
If we take 6012 away from 6120, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 12:
When dividing 1080 by 668, we get 1 with a remainder of 412.
Use 1 as the next digit of our solution. 
Result so far: 125085.9191
Deduct 668 from 1080 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 13:
668 can be fit into 4120 6 times, resulting in a remainder of 112.
The next digit of our result is 6. 
Result so far: 125085.91916
If we subtract 4008 from 4120, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 14:
If we divide 1120 by 668, we get 1 and a remainder of 452.
Write down 1 as next digit of the result. 
Result so far: 125085.919161
Subtract 668 from 1120 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 15:
4520 divided by 668 is 6 with a remainder of 512.
Record the quotient 6 as the next digit in the result. 
Result so far: 125085.9191616
Subtract 4008 from 4520 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 16:
If we divide 5120 by 668, we get 7 and a remainder of 444.
Record the quotient 7 as the next digit in the result. 
Result so far: 125085.91916167
Subtract 4676 from 5120 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

The quotient of the division is 125085.91916167, and the remainder is 4.44e-07.
