We look at the division of 315469 by 57 
The aim is to understand the frequency of 57 in 315469.

On to step 1:
When dividing 3 by 57, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 57

Advancing to step 2:
57 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 57

Advancing to step 3:
315 divided by 57 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 285 from 315 leaves us with 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 57

Moving on to step 4:
If we divide 304 by 57, we get 5 and a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 55.0
Deduct 285 from 304 and we're left with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 57

Let's proceed to step 5:
196 divided by 57 is 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 553.0
Subtract 171 from 196 to get 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 57

Step 6:
When dividing 259 by 57, we get 4 with a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 5534.0
The remainder is 31 after subtracting 228 from 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
When dividing 310 by 57, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 5534.5
The remainder is 25 after subtracting 285 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
The number 57 fits into 250 4 times, leaving a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 5534.54
Subtract 228 from 250 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
If we divide 220 by 57, we get 3 and a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 5534.543
If we take 171 away from 220, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 10:
57 can be fit into 490 8 times, resulting in a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 5534.5438
If we subtract 456 from 490, we get 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 11:
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: 5534.54385
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.

Going ahead to step 12:
When dividing 550 by 57, we get 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 5534.543859
If we subtract 513 from 550, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 13:
57 can be fit into 370 6 times, resulting in a remainder of 28.
The next digit of our result is 6. 
Result so far: 5534.5438596
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.

On to step 14:
The number 57 fits into 280 4 times, leaving a remainder of 52.
The next digit of our result is 4. 
Result so far: 5534.54385964
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.

In conclusion, the division gives 5534.54385964 with a balance of 5.2e-08.
