We look at the division of 484819 by 57 
The aim is to understand the frequency of 57 in 484819.

Going ahead to step 1:
57 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 57

Moving on to step 2:
When dividing 48 by 57, we get 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Fetch the next digit (4) from the dividend, attach it to 48 and continue: 484 / 57

Step 3:
57 goes into 484 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 456 from 484, we get 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 57

On to step 4:
57 goes into 288 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtracting 285 from 288 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 57

Let's proceed to step 5:
If we divide 31 by 57, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 850.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 57

Step 6:
319 divided by 57 is 5 with a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 8505.0
Subtracting 285 from 319 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
The number 57 fits into 340 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 8505.5
If we subtract 285 from 340, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 8:
When dividing 550 by 57, we get 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 8505.59
Subtracting 513 from 550 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
The number 57 fits into 370 6 times, leaving a remainder of 28.
The next digit of our result is 6. 
Result so far: 8505.596
If we take 342 away from 370, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
57 can be fit into 280 4 times, resulting in a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 8505.5964
Subtracting 228 from 280 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
When dividing 520 by 57, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 8505.59649
Deduct 513 from 520 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
57 can be fit into 70 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 8505.596491
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
57 can be fit into 130 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 8505.5964912
The remainder is 16 after subtracting 114 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
160 divided by 57 is 2 with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 8505.59649122
If we take 114 away from 160, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 8505.59649122, with a leftover of 4.6e-08.
