We look at the division of 497282 by 57 
The aim is to understand the frequency of 57 in 497282.

Advancing to step 1:
57 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 57

Advancing to step 2:
The number 57 fits into 49 0 times, leaving a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Fetch the next digit (7) from the dividend, attach it to 49 and continue: 497 / 57

Moving on to step 3:
57 can be fit into 497 8 times, resulting in a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 456 from 497, we get 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 57

Let's proceed to step 4:
The number 57 fits into 412 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Deduct 399 from 412 and we're left with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 57

Advancing to step 5:
138 divided by 57 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 872.0
Deduct 114 from 138 and we're left with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 57

Step 6:
The number 57 fits into 242 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 8724.0
Subtracting 228 from 242 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
57 can be fit into 140 2 times, resulting in a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 8724.2
The remainder is 26 after subtracting 114 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
The number 57 fits into 260 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 8724.24
The remainder is 32 after subtracting 228 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
57 goes into 320 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 8724.245
Deduct 285 from 320 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
350 divided by 57 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 8724.2456
Subtracting 342 from 350 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
57 goes into 80 1 times with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 8724.24561
If we subtract 57 from 80, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
57 can be fit into 230 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 8724.245614
If we subtract 228 from 230, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
When dividing 20 by 57, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8724.245614
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
The number 57 fits into 200 3 times, leaving a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 8724.24561403
If we take 171 away from 200, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 8724.24561403, with a leftover of 2.9e-08.
