We divide 508566 by 57
The aim is to understand the frequency of 57 in 508566.

Going ahead to step 1:
When dividing 5 by 57, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 57

Advancing to step 2:
57 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 57

Advancing to step 3:
57 can be fit into 508 8 times, resulting in a remainder of 52.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 456 from 508, we get 52.
Include the next digit (5) from the dividend after 52, then repeat: 525 / 57

Moving on to step 4:
57 can be fit into 525 9 times, resulting in a remainder of 12.
The next digit of our result is 9. 
Result so far: 89.0
Subtract 513 from 525 to get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 57

Let's proceed to step 5:
57 can be fit into 126 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 892.0
If we take 114 away from 126, we end up with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 57

Advancing to step 6:
57 can be fit into 126 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 8922.0
Deduct 114 from 126 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
If we divide 120 by 57, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 8922.2
The remainder is 6 after subtracting 114 from 120.
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 8:
If we divide 60 by 57, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 8922.21
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 9:
57 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 8922.21
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.

On to step 10:
57 can be fit into 300 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 8922.2105
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.

Step 11:
When dividing 150 by 57, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 8922.21052
The remainder is 36 after subtracting 114 from 150.
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 12:
If we divide 360 by 57, we get 6 and a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 8922.210526
Deduct 342 from 360 and we're left 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.

On to step 13:
57 goes into 180 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 8922.2105263
If we subtract 171 from 180, we get 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 14:
90 divided by 57 is 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 8922.21052631
If we take 57 away from 90, we end up 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.

The final outcome is 8922.21052631, with a leftover of 3.3e-08.
