We look at the division of 75849851 by 584 
The aim is to understand the frequency of 584 in 75849851.

Advancing to step 1:
7 divided by 584 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 584

Advancing to step 2:
75 divided by 584 is 0 with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Bring next digit (8) of the dividend behind the 75 and repeat the process: 758 / 584

Going ahead to step 3:
When dividing 758 by 584, we get 1 with a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 174 after subtracting 584 from 758.
Append the next digit (4) from the dividend to 174 and continue with: 1744 / 584

Going ahead to step 4:
If we divide 1744 by 584, we get 2 and a remainder of 576.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1168 from 1744 to get 576.
Take the next digit (9) from the dividend and append it to 576, then repeat: 5769 / 584

Advancing to step 5:
When dividing 5769 by 584, we get 9 with a remainder of 513.
The next digit of our result is 9. 
Result so far: 129.0
Subtracting 5256 from 5769 leaves us with 513.
Take the next digit (8) from the dividend and append it to 513, then repeat: 5138 / 584

Let's proceed to step 6:
584 can be fit into 5138 8 times, resulting in a remainder of 466.
The next digit of our result is 8. 
Result so far: 1298.0
The remainder is 466 after subtracting 4672 from 5138.
Append the next digit (5) from the dividend to 466 and continue with: 4665 / 584

Let's proceed to step 7:
The number 584 fits into 4665 7 times, leaving a remainder of 577.
Use 7 as the next digit of our solution. 
Result so far: 12987.0
Subtracting 4088 from 4665 leaves us with 577.
Take the next digit (1) from the dividend and append it to 577, then repeat: 5771 / 584

Going ahead to step 8:
The number 584 fits into 5771 9 times, leaving a remainder of 515.
Use 9 as the next digit of our solution. 
Result so far: 129879.0
If we subtract 5256 from 5771, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 9:
If we divide 5150 by 584, we get 8 and a remainder of 478.
The next digit of our result is 8. 
Result so far: 129879.8
If we subtract 4672 from 5150, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Let's proceed to step 10:
The number 584 fits into 4780 8 times, leaving a remainder of 108.
The number 8 becomes the next digit in our result. 
Result so far: 129879.88
Subtracting 4672 from 4780 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.

The final result is 129879.88 with a remainder of 0.108.
