We look at the division of 24628265 by 531 
The aim is to understand the frequency of 531 in 24628265.

Step 1:
When dividing 2 by 531, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 531

Step 2:
531 goes into 24 0 times with a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 531

Let's proceed to step 3:
When dividing 246 by 531, we get 0 with a remainder of 246.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 246 after subtracting 0 from 246.
Append the next digit (2) from the dividend to 246 and continue with: 2462 / 531

Advancing to step 4:
531 goes into 2462 4 times with a remainder of 338.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 2124 from 2462 leaves us with 338.
Take the next digit (8) from the dividend and append it to 338, then repeat: 3388 / 531

Let's proceed to step 5:
3388 divided by 531 is 6 with a remainder of 202.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we subtract 3186 from 3388, we get 202.
Take the next digit (2) from the dividend and append it to 202, then repeat: 2022 / 531

Advancing to step 6:
531 can be fit into 2022 3 times, resulting in a remainder of 429.
The number 3 becomes the next digit in our result. 
Result so far: 463.0
Subtract 1593 from 2022 to get 429.
Append the next digit (6) from the dividend to 429 and continue with: 4296 / 531

On to step 7:
If we divide 4296 by 531, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 4638.0
Subtracting 4248 from 4296 leaves us with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 531

Advancing to step 8:
485 divided by 531 is 0 with a remainder of 485.
Record the quotient 0 as the next digit in the result. 
Result so far: 46380.0
Deduct 0 from 485 and we're left with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 9:
4850 divided by 531 is 9 with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 46380.9
The remainder is 71 after subtracting 4779 from 4850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 10:
531 goes into 710 1 times with a remainder of 179.
Record the quotient 1 as the next digit in the result. 
Result so far: 46380.91
Subtract 531 from 710 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Step 11:
1790 divided by 531 is 3 with a remainder of 197.
The next digit of our result is 3. 
Result so far: 46380.913
The remainder is 197 after subtracting 1593 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 12:
1970 divided by 531 is 3 with a remainder of 377.
Write down 3 as next digit of the result. 
Result so far: 46380.9133
Deduct 1593 from 1970 and we're left with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

The final result is 46380.9133 with a remainder of 0.00377.
