We look at the division of 15073787 by 568 
The aim is to understand the frequency of 568 in 15073787.

Advancing to step 1:
1 divided by 568 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 568

Moving on to step 2:
When dividing 15 by 568, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 568

Advancing to step 3:
568 can be fit into 150 0 times, resulting in a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 150 to get 150.
Append the next digit (7) from the dividend to 150 and continue with: 1507 / 568

Moving on to step 4:
568 can be fit into 1507 2 times, resulting in a remainder of 371.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1136 from 1507 leaves us with 371.
Append the next digit (3) from the dividend to 371 and continue with: 3713 / 568

Advancing to step 5:
568 goes into 3713 6 times with a remainder of 305.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 3408 away from 3713, we end up with 305.
Include the next digit (7) from the dividend after 305, then repeat: 3057 / 568

On to step 6:
The number 568 fits into 3057 5 times, leaving a remainder of 217.
The number 5 becomes the next digit in our result. 
Result so far: 265.0
Subtracting 2840 from 3057 leaves us with 217.
Take the next digit (8) from the dividend and append it to 217, then repeat: 2178 / 568

Going ahead to step 7:
568 goes into 2178 3 times with a remainder of 474.
Record the quotient 3 as the next digit in the result. 
Result so far: 2653.0
If we subtract 1704 from 2178, we get 474.
Take the next digit (7) from the dividend and append it to 474, then repeat: 4747 / 568

Going ahead to step 8:
568 can be fit into 4747 8 times, resulting in a remainder of 203.
The number 8 becomes the next digit in our result. 
Result so far: 26538.0
The remainder is 203 after subtracting 4544 from 4747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Step 9:
If we divide 2030 by 568, we get 3 and a remainder of 326.
The next digit of our result is 3. 
Result so far: 26538.3
Subtract 1704 from 2030 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 10:
When dividing 3260 by 568, we get 5 with a remainder of 420.
Use 5 as the next digit of our solution. 
Result so far: 26538.35
If we take 2840 away from 3260, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 11:
The number 568 fits into 4200 7 times, leaving a remainder of 224.
Use 7 as the next digit of our solution. 
Result so far: 26538.357
If we subtract 3976 from 4200, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 12:
The number 568 fits into 2240 3 times, leaving a remainder of 536.
The number 3 becomes the next digit in our result. 
Result so far: 26538.3573
If we subtract 1704 from 2240, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 13:
If we divide 5360 by 568, we get 9 and a remainder of 248.
Use 9 as the next digit of our solution. 
Result so far: 26538.35739
Deduct 5112 from 5360 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 14:
568 goes into 2480 4 times with a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 26538.357394
The remainder is 208 after subtracting 2272 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 15:
568 can be fit into 2080 3 times, resulting in a remainder of 376.
Use 3 as the next digit of our solution. 
Result so far: 26538.3573943
If we take 1704 away from 2080, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 16:
When dividing 3760 by 568, we get 6 with a remainder of 352.
Record the quotient 6 as the next digit in the result. 
Result so far: 26538.35739436
Subtracting 3408 from 3760 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

After the division, we end up with 26538.35739436 and a remainder of 3.52e-07.
