We're dividing 730886 by 57 
The aim is to understand the frequency of 57 in 730886.

Advancing to step 1:
The number 57 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 57

Let's proceed to step 2:
The number 57 fits into 73 1 times, leaving a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 57 from 73, we get 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 57

Moving on to step 3:
57 goes into 160 2 times with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 114 from 160 leaves us with 46.
Include the next digit (8) from the dividend after 46, then repeat: 468 / 57

Step 4:
The number 57 fits into 468 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 128.0
Deduct 456 from 468 and we're left with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 57

Advancing to step 5:
57 goes into 128 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 1282.0
The remainder is 14 after subtracting 114 from 128.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 57

Advancing to step 6:
If we divide 146 by 57, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 12822.0
Subtract 114 from 146 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
If we divide 320 by 57, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 12822.5
If we take 285 away from 320, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
350 divided by 57 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 12822.56
Subtract 342 from 350 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 57, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 12822.561
Deduct 57 from 80 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 10:
When dividing 230 by 57, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 12822.5614
Subtracting 228 from 230 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
When dividing 20 by 57, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 12822.5614
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
57 goes into 200 3 times with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 12822.561403
The remainder is 29 after subtracting 171 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 13:
57 can be fit into 290 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12822.5614035
The remainder is 5 after subtracting 285 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
50 divided by 57 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 12822.5614035
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 12822.5614035 with a remainder of 5e-08.
