We look at the division of 985266 by 57 
The aim is to understand the frequency of 57 in 985266.

Going ahead to step 1:
57 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 57

Step 2:
If we divide 98 by 57, we get 1 and a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 57 from 98 leaves us with 41.
Take the next digit (5) from the dividend and append it to 41, then repeat: 415 / 57

Going ahead to step 3:
The number 57 fits into 415 7 times, leaving a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 399 from 415 leaves us with 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 57

Let's proceed to step 4:
The number 57 fits into 162 2 times, leaving a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Subtracting 114 from 162 leaves us with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 57

Let's proceed to step 5:
57 goes into 486 8 times with a remainder of 30.
The next digit of our result is 8. 
Result so far: 1728.0
Subtract 456 from 486 to get 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 57

On to step 6:
57 can be fit into 306 5 times, resulting in a remainder of 21.
The next digit of our result is 5. 
Result so far: 17285.0
Deduct 285 from 306 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.

Let's proceed to step 7:
The number 57 fits into 210 3 times, leaving a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 17285.3
The remainder is 39 after subtracting 171 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 8:
390 divided by 57 is 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 17285.36
If we subtract 342 from 390, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
The number 57 fits into 480 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 17285.368
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.

On to step 10:
240 divided by 57 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 17285.3684
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.

Going ahead to step 11:
120 divided by 57 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 17285.36842
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.

Step 12:
When dividing 60 by 57, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 17285.368421
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.

Step 13:
If we divide 30 by 57, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 17285.368421
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
When dividing 300 by 57, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 17285.36842105
If we subtract 285 from 300, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 17285.36842105 with a remainder of 1.5e-08.
