We're dividing 819360 by 57 
The aim is to understand the frequency of 57 in 819360.

Let's proceed to step 1:
57 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 57

Going ahead to step 2:
81 divided by 57 is 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 57 from 81 leaves us with 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 57

Going ahead to step 3:
57 goes into 249 4 times with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 228 away from 249, we end up with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 57

On to step 4:
57 can be fit into 213 3 times, resulting in a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 143.0
The remainder is 42 after subtracting 171 from 213.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 57

Step 5:
The number 57 fits into 426 7 times, leaving a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 1437.0
The remainder is 27 after subtracting 399 from 426.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 57

On to step 6:
The number 57 fits into 270 4 times, leaving a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 14374.0
Subtracting 228 from 270 leaves us 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.

Let's proceed to step 7:
420 divided by 57 is 7 with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 14374.7
Deduct 399 from 420 and we're left 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.

Advancing to step 8:
57 can be fit into 210 3 times, resulting in a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 14374.73
Subtract 171 from 210 to 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.

Step 9:
When dividing 390 by 57, we get 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 14374.736
If we take 342 away from 390, we end up 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:
The number 57 fits into 480 8 times, leaving a remainder of 24.
The next digit of our result is 8. 
Result so far: 14374.7368
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.

Advancing to step 11:
240 divided by 57 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 14374.73684
If we subtract 228 from 240, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
If we divide 120 by 57, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 14374.736842
Subtracting 114 from 120 leaves us with 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:
60 divided by 57 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 14374.7368421
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
57 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 14374.7368421
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 14374.7368421 with a balance of 3e-08.
