We look at the division of 319447 by 57 
The aim is to understand the frequency of 57 in 319447.

Going ahead to step 1:
The number 57 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 57

Going ahead to step 2:
57 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 57

Step 3:
The number 57 fits into 319 5 times, leaving a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 285 from 319 and we're left with 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 57

On to step 4:
When dividing 344 by 57, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 56.0
If we subtract 342 from 344, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 57

Step 5:
If we divide 24 by 57, we get 0 and a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 560.0
Deduct 0 from 24 and we're left with 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 57

Step 6:
If we divide 247 by 57, we get 4 and a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 5604.0
Subtracting 228 from 247 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
57 goes into 190 3 times with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 5604.3
If we subtract 171 from 190, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
The number 57 fits into 190 3 times, leaving a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 5604.33
Subtracting 171 from 190 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 5604.33 with a remaining 0.019.
