We look at the division of 52082976 by 57 
The aim is to understand the frequency of 57 in 52082976.

On to step 1:
When dividing 5 by 57, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 57

Advancing to step 2:
52 divided by 57 is 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 57

Advancing to step 3:
57 can be fit into 520 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 513 from 520 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 57

Moving on to step 4:
The number 57 fits into 78 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 91.0
If we take 57 away from 78, we end up with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 57

Going ahead to step 5:
57 can be fit into 212 3 times, resulting in a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 913.0
If we take 171 away from 212, we end up with 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 57

Advancing to step 6:
If we divide 419 by 57, we get 7 and a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 9137.0
If we subtract 399 from 419, we get 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 57

On to step 7:
If we divide 207 by 57, we get 3 and a remainder of 36.
The next digit of our result is 3. 
Result so far: 91373.0
Subtracting 171 from 207 leaves us with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 57

On to step 8:
The number 57 fits into 366 6 times, leaving a remainder of 24.
The next digit of our result is 6. 
Result so far: 913736.0
Deduct 342 from 366 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
If we divide 240 by 57, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 913736.4
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
120 divided by 57 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 913736.42
Subtract 114 from 120 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
The number 57 fits into 60 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 913736.421
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.

On to step 12:
If we divide 30 by 57, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 913736.421
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
57 can be fit into 300 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 913736.42105
The remainder is 15 after subtracting 285 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
150 divided by 57 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 913736.421052
Deduct 114 from 150 and we're left 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.

Going ahead to step 15:
If we divide 360 by 57, we get 6 and a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 913736.4210526
Subtracting 342 from 360 leaves us with 18.
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 16:
The number 57 fits into 180 3 times, leaving a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 913736.42105263
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.

The final outcome is 913736.42105263, with a leftover of 9e-09.
