We're dividing 82288638 by 531 
The aim is to understand the frequency of 531 in 82288638.

On to step 1:
If we divide 8 by 531, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 531

Going ahead to step 2:
The number 531 fits into 82 0 times, leaving a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Take the next digit (2) from the dividend and append it to 82, then repeat: 822 / 531

Step 3:
If we divide 822 by 531, we get 1 and a remainder of 291.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 291 after subtracting 531 from 822.
Include the next digit (8) from the dividend after 291, then repeat: 2918 / 531

On to step 4:
531 goes into 2918 5 times with a remainder of 263.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 2655 from 2918, we get 263.
Grab the next digit (8) from the dividend, add it to 263, then carry on: 2638 / 531

Step 5:
When dividing 2638 by 531, we get 4 with a remainder of 514.
Write down 4 as next digit of the result. 
Result so far: 154.0
Deduct 2124 from 2638 and we're left with 514.
Include the next digit (6) from the dividend after 514, then repeat: 5146 / 531

Step 6:
If we divide 5146 by 531, we get 9 and a remainder of 367.
Record the quotient 9 as the next digit in the result. 
Result so far: 1549.0
Deduct 4779 from 5146 and we're left with 367.
Append the next digit (3) from the dividend to 367 and continue with: 3673 / 531

On to step 7:
When dividing 3673 by 531, we get 6 with a remainder of 487.
Use 6 as the next digit of our solution. 
Result so far: 15496.0
Subtract 3186 from 3673 to get 487.
Append the next digit (8) from the dividend to 487 and continue with: 4878 / 531

Going ahead to step 8:
531 can be fit into 4878 9 times, resulting in a remainder of 99.
The next digit of our result is 9. 
Result so far: 154969.0
Subtracting 4779 from 4878 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
The number 531 fits into 990 1 times, leaving a remainder of 459.
Use 1 as the next digit of our solution. 
Result so far: 154969.1
If we take 531 away from 990, we end up with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Going ahead to step 10:
531 can be fit into 4590 8 times, resulting in a remainder of 342.
Put 8 as the next digit of the answer. 
Result so far: 154969.18
Subtract 4248 from 4590 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 11:
531 can be fit into 3420 6 times, resulting in a remainder of 234.
Record the quotient 6 as the next digit in the result. 
Result so far: 154969.186
Subtract 3186 from 3420 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 12:
When dividing 2340 by 531, we get 4 with a remainder of 216.
Record the quotient 4 as the next digit in the result. 
Result so far: 154969.1864
Subtract 2124 from 2340 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.

Step 13:
531 can be fit into 2160 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 154969.18644
The remainder is 36 after subtracting 2124 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 154969.18644, with a leftover of 3.6e-05.
