604197 ÷ 57 
The aim is to understand the frequency of 57 in 604197.

Advancing to step 1:
6 divided by 57 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 57

On to step 2:
57 can be fit into 60 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 57 from 60 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 57

Moving on to step 3:
When dividing 34 by 57, we get 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 34 after subtracting 0 from 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 57

Step 4:
If we divide 341 by 57, we get 5 and a remainder of 56.
Use 5 as the next digit of our solution. 
Result so far: 105.0
The remainder is 56 after subtracting 285 from 341.
Grab the next digit (9) from the dividend, add it to 56, then carry on: 569 / 57

On to step 5:
569 divided by 57 is 9 with a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 1059.0
Deduct 513 from 569 and we're left with 56.
Bring next digit (7) of the dividend behind the 56 and repeat the process: 567 / 57

Moving on to step 6:
57 goes into 567 9 times with a remainder of 54.
The next digit of our result is 9. 
Result so far: 10599.0
If we subtract 513 from 567, we get 54.
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 7:
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: 10599.9
If we take 513 away from 540, we end up 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.

Moving on to step 8:
When dividing 270 by 57, we get 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 10599.94
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.

Moving on to step 9:
57 can be fit into 420 7 times, resulting in a remainder of 21.
The next digit of our result is 7. 
Result so far: 10599.947
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.

Moving on to step 10:
210 divided by 57 is 3 with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 10599.9473
Deduct 171 from 210 and we're left 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.

Step 11:
57 goes into 390 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 10599.94736
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.

On to step 12:
When dividing 480 by 57, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 10599.947368
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.

Moving on to step 13:
If we divide 240 by 57, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 10599.9473684
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.

Moving on to step 14:
57 goes into 120 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 10599.94736842
If we take 114 away from 120, we end up 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.

Our division results in 10599.94736842 with a remaining 6e-09.
