330129 divided by 57 
The aim is to understand the frequency of 57 in 330129.

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
Deduct 0 from 3 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 57

Going ahead to step 2:
If we divide 33 by 57, we get 0 and a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 57

Going ahead to step 3:
When dividing 330 by 57, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 45 after subtracting 285 from 330.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 57

Step 4:
When dividing 451 by 57, we get 7 with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Deduct 399 from 451 and we're left with 52.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 57

Advancing to step 5:
If we divide 522 by 57, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 579.0
The remainder is 9 after subtracting 513 from 522.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 57

Let's proceed to step 6:
When dividing 99 by 57, we get 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 5791.0
If we take 57 away from 99, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
The number 57 fits into 420 7 times, leaving a remainder of 21.
The next digit of our result is 7. 
Result so far: 5791.7
If we subtract 399 from 420, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
If we divide 210 by 57, we get 3 and a remainder of 39.
The next digit of our result is 3. 
Result so far: 5791.73
If we subtract 171 from 210, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
When dividing 390 by 57, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 5791.736
Subtracting 342 from 390 leaves us with 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 10:
57 can be fit into 480 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 5791.7368
The remainder is 24 after subtracting 456 from 480.
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 11:
57 goes into 240 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 5791.73684
If we take 228 away from 240, we end up 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.

Step 12:
57 can be fit into 120 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 5791.736842
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
When dividing 60 by 57, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 5791.7368421
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
57 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 5791.7368421
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 5791.7368421 and a remainder of 3e-08.
