Let's divide 82537310 by 581
The aim is to understand the frequency of 581 in 82537310.

Moving on to step 1:
The number 581 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 581

Step 2:
If we divide 82 by 581, we get 0 and a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Append the next digit (5) from the dividend to 82 and continue with: 825 / 581

Moving on to step 3:
The number 581 fits into 825 1 times, leaving a remainder of 244.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 581 from 825 to get 244.
Grab the next digit (3) from the dividend, add it to 244, then carry on: 2443 / 581

On to step 4:
581 can be fit into 2443 4 times, resulting in a remainder of 119.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 119 after subtracting 2324 from 2443.
Append the next digit (7) from the dividend to 119 and continue with: 1197 / 581

Advancing to step 5:
When dividing 1197 by 581, we get 2 with a remainder of 35.
The next digit of our result is 2. 
Result so far: 142.0
Subtracting 1162 from 1197 leaves us with 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 581

Going ahead to step 6:
If we divide 353 by 581, we get 0 and a remainder of 353.
Write down 0 as next digit of the result. 
Result so far: 1420.0
The remainder is 353 after subtracting 0 from 353.
Fetch the next digit (1) from the dividend, attach it to 353 and continue: 3531 / 581

Advancing to step 7:
The number 581 fits into 3531 6 times, leaving a remainder of 45.
The next digit of our result is 6. 
Result so far: 14206.0
The remainder is 45 after subtracting 3486 from 3531.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 581

Let's proceed to step 8:
When dividing 450 by 581, we get 0 with a remainder of 450.
Record the quotient 0 as the next digit in the result. 
Result so far: 142060.0
Deduct 0 from 450 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 9:
4500 divided by 581 is 7 with a remainder of 433.
The number 7 becomes the next digit in our result. 
Result so far: 142060.7
Subtracting 4067 from 4500 leaves us with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 10:
If we divide 4330 by 581, we get 7 and a remainder of 263.
The next digit of our result is 7. 
Result so far: 142060.77
Subtract 4067 from 4330 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

The final outcome is 142060.77, with a leftover of 0.263.
