We look at the division of 15769563 by 584 
The aim is to understand the frequency of 584 in 15769563.

Moving on to step 1:
584 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
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 / 584

Advancing to step 2:
15 divided by 584 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 584

Step 3:
If we divide 157 by 584, we get 0 and a remainder of 157.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 157, we end up with 157.
Grab the next digit (6) from the dividend, add it to 157, then carry on: 1576 / 584

Step 4:
If we divide 1576 by 584, we get 2 and a remainder of 408.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1168 from 1576 to get 408.
Fetch the next digit (9) from the dividend, attach it to 408 and continue: 4089 / 584

Let's proceed to step 5:
584 goes into 4089 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 4088 from 4089 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 584

Let's proceed to step 6:
584 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 270.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 584

Going ahead to step 7:
584 can be fit into 156 0 times, resulting in a remainder of 156.
The number 0 becomes the next digit in our result. 
Result so far: 2700.0
Subtract 0 from 156 to get 156.
Append the next digit (3) from the dividend to 156 and continue with: 1563 / 584

Step 8:
584 can be fit into 1563 2 times, resulting in a remainder of 395.
Record the quotient 2 as the next digit in the result. 
Result so far: 27002.0
Deduct 1168 from 1563 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 9:
When dividing 3950 by 584, we get 6 with a remainder of 446.
Put 6 as the next digit of the answer. 
Result so far: 27002.6
Subtract 3504 from 3950 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 10:
If we divide 4460 by 584, we get 7 and a remainder of 372.
Write down 7 as next digit of the result. 
Result so far: 27002.67
Subtracting 4088 from 4460 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 11:
584 goes into 3720 6 times with a remainder of 216.
The number 6 becomes the next digit in our result. 
Result so far: 27002.676
Deduct 3504 from 3720 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 12:
When dividing 2160 by 584, we get 3 with a remainder of 408.
The next digit of our result is 3. 
Result so far: 27002.6763
The remainder is 408 after subtracting 1752 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 13:
4080 divided by 584 is 6 with a remainder of 576.
Use 6 as the next digit of our solution. 
Result so far: 27002.67636
Subtract 3504 from 4080 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

On to step 14:
584 can be fit into 5760 9 times, resulting in a remainder of 504.
The next digit of our result is 9. 
Result so far: 27002.676369
If we take 5256 away from 5760, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 15:
The number 584 fits into 5040 8 times, leaving a remainder of 368.
The number 8 becomes the next digit in our result. 
Result so far: 27002.6763698
Subtracting 4672 from 5040 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 16:
If we divide 3680 by 584, we get 6 and a remainder of 176.
Use 6 as the next digit of our solution. 
Result so far: 27002.67636986
If we take 3504 away from 3680, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final outcome is 27002.67636986, with a leftover of 1.76e-07.
