We look at the division of 208825 by 57 
The aim is to understand the frequency of 57 in 208825.

Step 1:
57 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 57

On to step 2:
The number 57 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 57

Moving on to step 3:
If we divide 208 by 57, we get 3 and a remainder of 37.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 171 from 208 to get 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 57

Moving on to step 4:
57 can be fit into 378 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
The remainder is 36 after subtracting 342 from 378.
Fetch the next digit (2) from the dividend, attach it to 36 and continue: 362 / 57

Advancing to step 5:
57 goes into 362 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 366.0
Subtracting 342 from 362 leaves us with 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 57

On to step 6:
When dividing 205 by 57, we get 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 3663.0
Subtracting 171 from 205 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.

Moving on to step 7:
If we divide 340 by 57, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 3663.5
Subtracting 285 from 340 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
57 can be fit into 550 9 times, resulting in a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 3663.59
Deduct 513 from 550 and we're left 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.

Moving on to step 9:
57 goes into 370 6 times with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 3663.596
If we subtract 342 from 370, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
280 divided by 57 is 4 with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 3663.5964
The remainder is 52 after subtracting 228 from 280.
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:
520 divided by 57 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 3663.59649
If we subtract 513 from 520, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
70 divided by 57 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 3663.596491
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 13:
When dividing 130 by 57, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 3663.5964912
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
57 goes into 160 2 times with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 3663.59649122
Deduct 114 from 160 and we're left 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.

Our division results in 3663.59649122 with a remaining 4.6e-08.
