We're dividing 27931254 by 581 
The aim is to understand the frequency of 581 in 27931254.

Advancing to step 1:
The number 581 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 581

Going ahead to step 2:
581 can be fit into 27 0 times, resulting in a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 581

Moving on to step 3:
If we divide 279 by 581, we get 0 and a remainder of 279.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 279 after subtracting 0 from 279.
Include the next digit (3) from the dividend after 279, then repeat: 2793 / 581

Advancing to step 4:
2793 divided by 581 is 4 with a remainder of 469.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 2324 from 2793 leaves us with 469.
Take the next digit (1) from the dividend and append it to 469, then repeat: 4691 / 581

Let's proceed to step 5:
581 goes into 4691 8 times with a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtract 4648 from 4691 to get 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 581

Advancing to step 6:
The number 581 fits into 432 0 times, leaving a remainder of 432.
The number 0 becomes the next digit in our result. 
Result so far: 480.0
Deduct 0 from 432 and we're left with 432.
Grab the next digit (5) from the dividend, add it to 432, then carry on: 4325 / 581

Going ahead to step 7:
If we divide 4325 by 581, we get 7 and a remainder of 258.
Write down 7 as next digit of the result. 
Result so far: 4807.0
Subtract 4067 from 4325 to get 258.
Fetch the next digit (4) from the dividend, attach it to 258 and continue: 2584 / 581

On to step 8:
2584 divided by 581 is 4 with a remainder of 260.
Write down 4 as next digit of the result. 
Result so far: 48074.0
If we subtract 2324 from 2584, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 9:
If we divide 2600 by 581, we get 4 and a remainder of 276.
Record the quotient 4 as the next digit in the result. 
Result so far: 48074.4
If we subtract 2324 from 2600, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 10:
2760 divided by 581 is 4 with a remainder of 436.
Write down 4 as next digit of the result. 
Result so far: 48074.44
Subtracting 2324 from 2760 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

The final outcome is 48074.44, with a leftover of 0.436.
