We look at the division of 548175 by 57 
The aim is to understand the frequency of 57 in 548175.

Moving on to step 1:
57 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
Deduct 0 from 5 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 57

Step 2:
If we divide 54 by 57, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 57

Going ahead to step 3:
548 divided by 57 is 9 with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 513 from 548 and we're left with 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 57

Let's proceed to step 4:
57 can be fit into 351 6 times, resulting in a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Deduct 342 from 351 and we're left with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 57

Step 5:
57 can be fit into 97 1 times, resulting in a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 961.0
The remainder is 40 after subtracting 57 from 97.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 57

Advancing to step 6:
405 divided by 57 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 9617.0
The remainder is 6 after subtracting 399 from 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
When dividing 60 by 57, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 9617.1
Subtract 57 from 60 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
57 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 9617.1
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
When dividing 300 by 57, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 9617.105
Subtract 285 from 300 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
57 goes into 150 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 9617.1052
Subtracting 114 from 150 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
57 goes into 360 6 times with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 9617.10526
The remainder is 18 after subtracting 342 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
57 goes into 180 3 times with a remainder of 9.
The next digit of our result is 3. 
Result so far: 9617.105263
Subtracting 171 from 180 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
The number 57 fits into 90 1 times, leaving a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 9617.1052631
Subtracting 57 from 90 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 14:
330 divided by 57 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 9617.10526315
Subtracting 285 from 330 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 9617.10526315, with a leftover of 4.5e-08.
