We're dividing 7359335 by 581 
The aim is to understand the frequency of 581 in 7359335.

Let's proceed to step 1:
If we divide 7 by 581, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 581

Step 2:
581 goes into 73 0 times with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 581

Let's proceed to step 3:
581 can be fit into 735 1 times, resulting in a remainder of 154.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 581 from 735 leaves us with 154.
Append the next digit (9) from the dividend to 154 and continue with: 1549 / 581

Going ahead to step 4:
When dividing 1549 by 581, we get 2 with a remainder of 387.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1162 from 1549 to get 387.
Append the next digit (3) from the dividend to 387 and continue with: 3873 / 581

Moving on to step 5:
581 can be fit into 3873 6 times, resulting in a remainder of 387.
Write down 6 as next digit of the result. 
Result so far: 126.0
The remainder is 387 after subtracting 3486 from 3873.
Append the next digit (3) from the dividend to 387 and continue with: 3873 / 581

Moving on to step 6:
When dividing 3873 by 581, we get 6 with a remainder of 387.
Record the quotient 6 as the next digit in the result. 
Result so far: 1266.0
The remainder is 387 after subtracting 3486 from 3873.
Take the next digit (5) from the dividend and append it to 387, then repeat: 3875 / 581

Going ahead to step 7:
If we divide 3875 by 581, we get 6 and a remainder of 389.
Put 6 as the next digit of the answer. 
Result so far: 12666.0
Subtracting 3486 from 3875 leaves us with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

On to step 8:
581 goes into 3890 6 times with a remainder of 404.
Write down 6 as next digit of the result. 
Result so far: 12666.6
If we take 3486 away from 3890, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 9:
4040 divided by 581 is 6 with a remainder of 554.
The next digit of our result is 6. 
Result so far: 12666.66
If we subtract 3486 from 4040, we get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

The final outcome is 12666.66, with a leftover of 0.554.
