We look at the division of 552365 by 57 
The aim is to understand the frequency of 57 in 552365.

Going ahead to step 1:
5 divided by 57 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 57

Advancing to step 2:
When dividing 55 by 57, we get 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 57

On to step 3:
57 goes into 552 9 times with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 513 from 552 leaves us with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 57

Advancing to step 4:
The number 57 fits into 393 6 times, leaving a remainder of 51.
The next digit of our result is 6. 
Result so far: 96.0
Subtract 342 from 393 to get 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 57

Going ahead to step 5:
If we divide 516 by 57, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 969.0
Subtract 513 from 516 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 57

On to step 6:
The number 57 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 9690.0
Deduct 0 from 35 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.

On to step 7:
If we divide 350 by 57, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 9690.6
The remainder is 8 after subtracting 342 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
80 divided by 57 is 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 9690.61
Subtracting 57 from 80 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
57 can be fit into 230 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 9690.614
If we take 228 away from 230, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
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: 9690.614
If we take 0 away from 20, we end up with 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 11:
57 can be fit into 200 3 times, resulting in a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 9690.61403
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.

Moving on to step 12:
The number 57 fits into 290 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 9690.614035
The remainder is 5 after subtracting 285 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
The number 57 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 9690.614035
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
The number 57 fits into 500 8 times, leaving a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 9690.61403508
If we take 456 away from 500, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 9690.61403508 with a remaining 4.4e-08.
