We're dividing 3452560 by 581 
The aim is to understand the frequency of 581 in 3452560.

On to step 1:
3 divided by 581 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 581

Advancing to step 2:
581 can be fit into 34 0 times, resulting in a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 581

Advancing to step 3:
345 divided by 581 is 0 with a remainder of 345.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 345 leaves us with 345.
Append the next digit (2) from the dividend to 345 and continue with: 3452 / 581

Step 4:
3452 divided by 581 is 5 with a remainder of 547.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 2905 from 3452 to get 547.
Grab the next digit (5) from the dividend, add it to 547, then carry on: 5475 / 581

Moving on to step 5:
581 can be fit into 5475 9 times, resulting in a remainder of 246.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Deduct 5229 from 5475 and we're left with 246.
Take the next digit (6) from the dividend and append it to 246, then repeat: 2466 / 581

Advancing to step 6:
581 goes into 2466 4 times with a remainder of 142.
The next digit of our result is 4. 
Result so far: 594.0
If we take 2324 away from 2466, we end up with 142.
Append the next digit (0) from the dividend to 142 and continue with: 1420 / 581

Let's proceed to step 7:
581 goes into 1420 2 times with a remainder of 258.
Use 2 as the next digit of our solution. 
Result so far: 5942.0
The remainder is 258 after subtracting 1162 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 8:
The number 581 fits into 2580 4 times, leaving a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 5942.4
Subtracting 2324 from 2580 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 9:
If we divide 2560 by 581, we get 4 and a remainder of 236.
The number 4 becomes the next digit in our result. 
Result so far: 5942.44
Subtracting 2324 from 2560 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final result is 5942.44 with a remainder of 0.236.
