We're dividing 83112103 by 668 
The aim is to understand the frequency of 668 in 83112103.

Advancing to step 1:
668 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 668

On to step 2:
If we divide 83 by 668, we get 0 and a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 668

Moving on to step 3:
The number 668 fits into 831 1 times, leaving a remainder of 163.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 668 from 831 and we're left with 163.
Fetch the next digit (1) from the dividend, attach it to 163 and continue: 1631 / 668

On to step 4:
668 can be fit into 1631 2 times, resulting in a remainder of 295.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 1336 from 1631 to get 295.
Bring next digit (2) of the dividend behind the 295 and repeat the process: 2952 / 668

Step 5:
If we divide 2952 by 668, we get 4 and a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 124.0
If we subtract 2672 from 2952, we get 280.
Bring next digit (1) of the dividend behind the 280 and repeat the process: 2801 / 668

Moving on to step 6:
When dividing 2801 by 668, we get 4 with a remainder of 129.
Use 4 as the next digit of our solution. 
Result so far: 1244.0
Subtracting 2672 from 2801 leaves us with 129.
Take the next digit (0) from the dividend and append it to 129, then repeat: 1290 / 668

Let's proceed to step 7:
The number 668 fits into 1290 1 times, leaving a remainder of 622.
The number 1 becomes the next digit in our result. 
Result so far: 12441.0
Subtract 668 from 1290 to get 622.
Fetch the next digit (3) from the dividend, attach it to 622 and continue: 6223 / 668

Let's proceed to step 8:
If we divide 6223 by 668, we get 9 and a remainder of 211.
Put 9 as the next digit of the answer. 
Result so far: 124419.0
If we take 6012 away from 6223, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 9:
668 goes into 2110 3 times with a remainder of 106.
The number 3 becomes the next digit in our result. 
Result so far: 124419.3
The remainder is 106 after subtracting 2004 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 10:
668 goes into 1060 1 times with a remainder of 392.
Use 1 as the next digit of our solution. 
Result so far: 124419.31
If we take 668 away from 1060, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 11:
When dividing 3920 by 668, we get 5 with a remainder of 580.
Write down 5 as next digit of the result. 
Result so far: 124419.315
Subtracting 3340 from 3920 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 12:
5800 divided by 668 is 8 with a remainder of 456.
The number 8 becomes the next digit in our result. 
Result so far: 124419.3158
Subtract 5344 from 5800 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 13:
When dividing 4560 by 668, we get 6 with a remainder of 552.
Write down 6 as next digit of the result. 
Result so far: 124419.31586
If we subtract 4008 from 4560, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 14:
668 goes into 5520 8 times with a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 124419.315868
If we take 5344 away from 5520, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 15:
1760 divided by 668 is 2 with a remainder of 424.
The number 2 becomes the next digit in our result. 
Result so far: 124419.3158682
Subtracting 1336 from 1760 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 16:
4240 divided by 668 is 6 with a remainder of 232.
Write down 6 as next digit of the result. 
Result so far: 124419.31586826
Deduct 4008 from 4240 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The final result is 124419.31586826 with a remainder of 2.32e-07.
