We look at the division of 57524445 by 431 
The aim is to understand the frequency of 431 in 57524445.

Let's proceed to step 1:
431 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 431

Step 2:
431 can be fit into 57 0 times, resulting in a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 431

Moving on to step 3:
If we divide 575 by 431, we get 1 and a remainder of 144.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 431 away from 575, we end up with 144.
Bring next digit (2) of the dividend behind the 144 and repeat the process: 1442 / 431

Advancing to step 4:
If we divide 1442 by 431, we get 3 and a remainder of 149.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 1293 from 1442 to get 149.
Append the next digit (4) from the dividend to 149 and continue with: 1494 / 431

On to step 5:
If we divide 1494 by 431, we get 3 and a remainder of 201.
The next digit of our result is 3. 
Result so far: 133.0
Deduct 1293 from 1494 and we're left with 201.
Bring next digit (4) of the dividend behind the 201 and repeat the process: 2014 / 431

Going ahead to step 6:
When dividing 2014 by 431, we get 4 with a remainder of 290.
The number 4 becomes the next digit in our result. 
Result so far: 1334.0
Deduct 1724 from 2014 and we're left with 290.
Take the next digit (4) from the dividend and append it to 290, then repeat: 2904 / 431

On to step 7:
2904 divided by 431 is 6 with a remainder of 318.
The next digit of our result is 6. 
Result so far: 13346.0
If we take 2586 away from 2904, we end up with 318.
Include the next digit (5) from the dividend after 318, then repeat: 3185 / 431

Moving on to step 8:
The number 431 fits into 3185 7 times, leaving a remainder of 168.
Write down 7 as next digit of the result. 
Result so far: 133467.0
The remainder is 168 after subtracting 3017 from 3185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 9:
The number 431 fits into 1680 3 times, leaving a remainder of 387.
The number 3 becomes the next digit in our result. 
Result so far: 133467.3
The remainder is 387 after subtracting 1293 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Moving on to step 10:
When dividing 3870 by 431, we get 8 with a remainder of 422.
The number 8 becomes the next digit in our result. 
Result so far: 133467.38
The remainder is 422 after subtracting 3448 from 3870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Advancing to step 11:
The number 431 fits into 4220 9 times, leaving a remainder of 341.
Record the quotient 9 as the next digit in the result. 
Result so far: 133467.389
The remainder is 341 after subtracting 3879 from 4220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Going ahead to step 12:
When dividing 3410 by 431, we get 7 with a remainder of 393.
Use 7 as the next digit of our solution. 
Result so far: 133467.3897
Deduct 3017 from 3410 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Moving on to step 13:
3930 divided by 431 is 9 with a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 133467.38979
Subtract 3879 from 3930 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 14:
The number 431 fits into 510 1 times, leaving a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 133467.389791
If we subtract 431 from 510, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 15:
If we divide 790 by 431, we get 1 and a remainder of 359.
Write down 1 as next digit of the result. 
Result so far: 133467.3897911
If we subtract 431 from 790, we get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

The final outcome is 133467.3897911, with a leftover of 3.59e-06.
