We're dividing 28797841 by 668 
The aim is to understand the frequency of 668 in 28797841.

Advancing to step 1:
The number 668 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 668

Advancing to step 2:
668 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 668

Step 3:
668 goes into 287 0 times with a remainder of 287.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 287 after subtracting 0 from 287.
Append the next digit (9) from the dividend to 287 and continue with: 2879 / 668

Going ahead to step 4:
The number 668 fits into 2879 4 times, leaving a remainder of 207.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 207 after subtracting 2672 from 2879.
Take the next digit (7) from the dividend and append it to 207, then repeat: 2077 / 668

On to step 5:
The number 668 fits into 2077 3 times, leaving a remainder of 73.
The next digit of our result is 3. 
Result so far: 43.0
If we take 2004 away from 2077, we end up with 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 668

Moving on to step 6:
When dividing 738 by 668, we get 1 with a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 431.0
If we subtract 668 from 738, we get 70.
Grab the next digit (4) from the dividend, add it to 70, then carry on: 704 / 668

Moving on to step 7:
668 can be fit into 704 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 4311.0
Subtracting 668 from 704 leaves us with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 668

Going ahead to step 8:
If we divide 361 by 668, we get 0 and a remainder of 361.
Use 0 as the next digit of our solution. 
Result so far: 43110.0
Deduct 0 from 361 and we're left with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

On to step 9:
The number 668 fits into 3610 5 times, leaving a remainder of 270.
The number 5 becomes the next digit in our result. 
Result so far: 43110.5
Subtracting 3340 from 3610 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 10:
If we divide 2700 by 668, we get 4 and a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 43110.54
Subtracting 2672 from 2700 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
The number 668 fits into 280 0 times, leaving a remainder of 280.
The next digit of our result is 0. 
Result so far: 43110.54
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
The number 668 fits into 2800 4 times, leaving a remainder of 128.
The next digit of our result is 4. 
Result so far: 43110.5404
Deduct 2672 from 2800 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.

Advancing to step 13:
When dividing 1280 by 668, we get 1 with a remainder of 612.
The next digit of our result is 1. 
Result so far: 43110.54041
If we take 668 away from 1280, we end up with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Moving on to step 14:
668 can be fit into 6120 9 times, resulting in a remainder of 108.
Record the quotient 9 as the next digit in the result. 
Result so far: 43110.540419
Subtracting 6012 from 6120 leaves us 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.

Let's proceed to step 15:
668 goes into 1080 1 times with a remainder of 412.
The number 1 becomes the next digit in our result. 
Result so far: 43110.5404191
Subtracting 668 from 1080 leaves us 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.

Going ahead to step 16:
When dividing 4120 by 668, we get 6 with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 43110.54041916
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.

After the division, we end up with 43110.54041916 and a remainder of 1.12e-07.
