We look at the division of 28921073 by 527 
The aim is to understand the frequency of 527 in 28921073.

Advancing to step 1:
When dividing 2 by 527, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 527

Moving on to step 2:
When dividing 28 by 527, we get 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 527

On to step 3:
289 divided by 527 is 0 with a remainder of 289.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 289 and we're left with 289.
Bring next digit (2) of the dividend behind the 289 and repeat the process: 2892 / 527

Going ahead to step 4:
2892 divided by 527 is 5 with a remainder of 257.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 2635 from 2892 and we're left with 257.
Include the next digit (1) from the dividend after 257, then repeat: 2571 / 527

Going ahead to step 5:
2571 divided by 527 is 4 with a remainder of 463.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Subtract 2108 from 2571 to get 463.
Fetch the next digit (0) from the dividend, attach it to 463 and continue: 4630 / 527

Moving on to step 6:
527 goes into 4630 8 times with a remainder of 414.
Put 8 as the next digit of the answer. 
Result so far: 548.0
Deduct 4216 from 4630 and we're left with 414.
Bring next digit (7) of the dividend behind the 414 and repeat the process: 4147 / 527

On to step 7:
When dividing 4147 by 527, we get 7 with a remainder of 458.
The number 7 becomes the next digit in our result. 
Result so far: 5487.0
The remainder is 458 after subtracting 3689 from 4147.
Grab the next digit (3) from the dividend, add it to 458, then carry on: 4583 / 527

Moving on to step 8:
527 can be fit into 4583 8 times, resulting in a remainder of 367.
Record the quotient 8 as the next digit in the result. 
Result so far: 54878.0
If we take 4216 away from 4583, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Moving on to step 9:
When dividing 3670 by 527, we get 6 with a remainder of 508.
Write down 6 as next digit of the result. 
Result so far: 54878.6
If we take 3162 away from 3670, we end up with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Step 10:
If we divide 5080 by 527, we get 9 and a remainder of 337.
The number 9 becomes the next digit in our result. 
Result so far: 54878.69
If we subtract 4743 from 5080, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Advancing to step 11:
If we divide 3370 by 527, we get 6 and a remainder of 208.
Record the quotient 6 as the next digit in the result. 
Result so far: 54878.696
Subtract 3162 from 3370 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 12:
2080 divided by 527 is 3 with a remainder of 499.
The number 3 becomes the next digit in our result. 
Result so far: 54878.6963
Deduct 1581 from 2080 and we're left with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

On to step 13:
527 can be fit into 4990 9 times, resulting in a remainder of 247.
The number 9 becomes the next digit in our result. 
Result so far: 54878.69639
If we take 4743 away from 4990, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 14:
If we divide 2470 by 527, we get 4 and a remainder of 362.
The number 4 becomes the next digit in our result. 
Result so far: 54878.696394
If we take 2108 away from 2470, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 15:
If we divide 3620 by 527, we get 6 and a remainder of 458.
Use 6 as the next digit of our solution. 
Result so far: 54878.6963946
Subtracting 3162 from 3620 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 16:
The number 527 fits into 4580 8 times, leaving a remainder of 364.
The next digit of our result is 8. 
Result so far: 54878.69639468
Subtracting 4216 from 4580 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

In conclusion, the division gives 54878.69639468 with a balance of 3.64e-07.
