549245 divided by 57 
The aim is to understand the frequency of 57 in 549245.

On to step 1:
57 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 57

Let's proceed to step 2:
If we divide 54 by 57, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 57

Moving on to step 3:
57 can be fit into 549 9 times, resulting in a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 513 from 549, we get 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 57

Advancing to step 4:
57 can be fit into 362 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 96.0
Deduct 342 from 362 and we're left with 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 57

Step 5:
57 goes into 204 3 times with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 963.0
Subtract 171 from 204 to get 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 57

Going ahead to step 6:
57 can be fit into 335 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 9635.0
Subtracting 285 from 335 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
The number 57 fits into 500 8 times, leaving a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 9635.8
The remainder is 44 after subtracting 456 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 8:
57 goes into 440 7 times with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 9635.87
Subtracting 399 from 440 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
The number 57 fits into 410 7 times, leaving a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 9635.877
Deduct 399 from 410 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 9635.877 and a remainder of 0.0011.
