We look at the division of 84901135 by 568 
The aim is to understand the frequency of 568 in 84901135.

Advancing to step 1:
568 can be fit into 8 0 times, resulting in 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.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 568

On to step 2:
84 divided by 568 is 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Fetch the next digit (9) from the dividend, attach it to 84 and continue: 849 / 568

On to step 3:
If we divide 849 by 568, we get 1 and a remainder of 281.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 568 from 849 leaves us with 281.
Include the next digit (0) from the dividend after 281, then repeat: 2810 / 568

Let's proceed to step 4:
If we divide 2810 by 568, we get 4 and a remainder of 538.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 2272 away from 2810, we end up with 538.
Include the next digit (1) from the dividend after 538, then repeat: 5381 / 568

Step 5:
If we divide 5381 by 568, we get 9 and a remainder of 269.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
If we subtract 5112 from 5381, we get 269.
Include the next digit (1) from the dividend after 269, then repeat: 2691 / 568

Let's proceed to step 6:
When dividing 2691 by 568, we get 4 with a remainder of 419.
The number 4 becomes the next digit in our result. 
Result so far: 1494.0
Subtract 2272 from 2691 to get 419.
Bring next digit (3) of the dividend behind the 419 and repeat the process: 4193 / 568

Moving on to step 7:
568 can be fit into 4193 7 times, resulting in a remainder of 217.
Put 7 as the next digit of the answer. 
Result so far: 14947.0
The remainder is 217 after subtracting 3976 from 4193.
Bring next digit (5) of the dividend behind the 217 and repeat the process: 2175 / 568

Step 8:
The number 568 fits into 2175 3 times, leaving a remainder of 471.
The next digit of our result is 3. 
Result so far: 149473.0
Deduct 1704 from 2175 and we're left with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Step 9:
568 goes into 4710 8 times with a remainder of 166.
The next digit of our result is 8. 
Result so far: 149473.8
Deduct 4544 from 4710 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 10:
1660 divided by 568 is 2 with a remainder of 524.
Put 2 as the next digit of the answer. 
Result so far: 149473.82
The remainder is 524 after subtracting 1136 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Going ahead to step 11:
5240 divided by 568 is 9 with a remainder of 128.
Use 9 as the next digit of our solution. 
Result so far: 149473.829
The remainder is 128 after subtracting 5112 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 12:
If we divide 1280 by 568, we get 2 and a remainder of 144.
The number 2 becomes the next digit in our result. 
Result so far: 149473.8292
Subtract 1136 from 1280 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 13:
If we divide 1440 by 568, we get 2 and a remainder of 304.
Use 2 as the next digit of our solution. 
Result so far: 149473.82922
Subtract 1136 from 1440 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final result is 149473.82922 with a remainder of 0.000304.
