We look at the division of 80935530 by 584 
The aim is to understand the frequency of 584 in 80935530.

On to step 1:
584 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 584

Moving on to step 2:
If we divide 80 by 584, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 584

Moving on to step 3:
809 divided by 584 is 1 with a remainder of 225.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 584 from 809 leaves us with 225.
Include the next digit (3) from the dividend after 225, then repeat: 2253 / 584

Going ahead to step 4:
If we divide 2253 by 584, we get 3 and a remainder of 501.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1752 away from 2253, we end up with 501.
Append the next digit (5) from the dividend to 501 and continue with: 5015 / 584

Moving on to step 5:
584 goes into 5015 8 times with a remainder of 343.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Subtract 4672 from 5015 to get 343.
Bring next digit (5) of the dividend behind the 343 and repeat the process: 3435 / 584

Step 6:
584 can be fit into 3435 5 times, resulting in a remainder of 515.
Write down 5 as next digit of the result. 
Result so far: 1385.0
Subtract 2920 from 3435 to get 515.
Grab the next digit (3) from the dividend, add it to 515, then carry on: 5153 / 584

Moving on to step 7:
When dividing 5153 by 584, we get 8 with a remainder of 481.
Use 8 as the next digit of our solution. 
Result so far: 13858.0
Deduct 4672 from 5153 and we're left with 481.
Grab the next digit (0) from the dividend, add it to 481, then carry on: 4810 / 584

Step 8:
When dividing 4810 by 584, we get 8 with a remainder of 138.
The next digit of our result is 8. 
Result so far: 138588.0
The remainder is 138 after subtracting 4672 from 4810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 9:
1380 divided by 584 is 2 with a remainder of 212.
The number 2 becomes the next digit in our result. 
Result so far: 138588.2
The remainder is 212 after subtracting 1168 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 10:
When dividing 2120 by 584, we get 3 with a remainder of 368.
Record the quotient 3 as the next digit in the result. 
Result so far: 138588.23
If we take 1752 away from 2120, we end up 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.

Advancing to step 11:
When dividing 3680 by 584, we get 6 with a remainder of 176.
Write down 6 as next digit of the result. 
Result so far: 138588.236
Subtracting 3504 from 3680 leaves us 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.

Going ahead to step 12:
1760 divided by 584 is 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 138588.2363
If we subtract 1752 from 1760, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
584 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 138588.2363
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
584 goes into 800 1 times with a remainder of 216.
Write down 1 as next digit of the result. 
Result so far: 138588.236301
Subtract 584 from 800 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 15:
584 can be fit into 2160 3 times, resulting in a remainder of 408.
Record the quotient 3 as the next digit in the result. 
Result so far: 138588.2363013
If we subtract 1752 from 2160, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 16:
4080 divided by 584 is 6 with a remainder of 576.
Put 6 as the next digit of the answer. 
Result so far: 138588.23630136
Deduct 3504 from 4080 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The final result is 138588.23630136 with a remainder of 5.76e-07.
