788298 ÷ 57 
The aim is to understand the frequency of 57 in 788298.

Let's proceed to step 1:
The number 57 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 57

Advancing to step 2:
57 goes into 78 1 times with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 21 after subtracting 57 from 78.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 57

Moving on to step 3:
218 divided by 57 is 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 47 after subtracting 171 from 218.
Append the next digit (2) from the dividend to 47 and continue with: 472 / 57

On to step 4:
472 divided by 57 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Subtract 456 from 472 to get 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 57

Let's proceed to step 5:
57 can be fit into 169 2 times, resulting in a remainder of 55.
The number 2 becomes the next digit in our result. 
Result so far: 1382.0
Subtract 114 from 169 to get 55.
Fetch the next digit (8) from the dividend, attach it to 55 and continue: 558 / 57

Let's proceed to step 6:
57 goes into 558 9 times with a remainder of 45.
The next digit of our result is 9. 
Result so far: 13829.0
If we take 513 away from 558, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
When dividing 450 by 57, we get 7 with a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 13829.7
If we take 399 away from 450, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 8:
The number 57 fits into 510 8 times, leaving a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 13829.78
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.

Let's proceed to step 9:
If we divide 540 by 57, we get 9 and a remainder of 27.
The next digit of our result is 9. 
Result so far: 13829.789
Deduct 513 from 540 and we're left with 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 10:
If we divide 270 by 57, we get 4 and a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 13829.7894
Deduct 228 from 270 and we're left 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.

On to step 11:
57 goes into 420 7 times with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 13829.78947
Subtract 399 from 420 to 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.

Advancing to step 12:
57 can be fit into 210 3 times, resulting in a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 13829.789473
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 13:
When dividing 390 by 57, we get 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 13829.7894736
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 14:
When dividing 480 by 57, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 13829.78947368
If we subtract 456 from 480, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 13829.78947368 with a remaining 2.4e-08.
