We look at the division of 174072 by 57 
The aim is to understand the frequency of 57 in 174072.

Advancing to step 1:
When dividing 1 by 57, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 57

Let's proceed to step 2:
The number 57 fits into 17 0 times, leaving a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 57

On to step 3:
57 goes into 174 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 3 after subtracting 171 from 174.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 57

Advancing to step 4:
If we divide 30 by 57, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 30 and we're left with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 57

On to step 5:
57 goes into 307 5 times with a remainder of 22.
The next digit of our result is 5. 
Result so far: 305.0
If we take 285 away from 307, we end up with 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 57

Let's proceed to step 6:
When dividing 222 by 57, we get 3 with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 3053.0
The remainder is 51 after subtracting 171 from 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
57 can be fit into 510 8 times, resulting in a remainder of 54.
The next digit of our result is 8. 
Result so far: 3053.8
The remainder is 54 after subtracting 456 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
540 divided by 57 is 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 3053.89
Subtract 513 from 540 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
270 divided by 57 is 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 3053.894
The remainder is 42 after subtracting 228 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
If we divide 420 by 57, we get 7 and a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 3053.8947
If we take 399 away from 420, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
57 goes into 210 3 times with a remainder of 39.
The next digit of our result is 3. 
Result so far: 3053.89473
If we take 171 away from 210, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 12:
If we divide 390 by 57, we get 6 and a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 3053.894736
Subtract 342 from 390 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
When dividing 480 by 57, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 3053.8947368
Subtracting 456 from 480 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
57 goes into 240 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 3053.89473684
Deduct 228 from 240 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 3053.89473684 with a remainder of 1.2e-08.
