We look at the division of 804149 by 57 
The aim is to understand the frequency of 57 in 804149.

Let's proceed to step 1:
The number 57 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 57

On to step 2:
57 goes into 80 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 57 away from 80, we end up with 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 57

Let's proceed to step 3:
234 divided by 57 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 228 from 234, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 57

Advancing to step 4:
If we divide 61 by 57, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 141.0
If we subtract 57 from 61, we get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 57

Let's proceed to step 5:
The number 57 fits into 44 0 times, leaving a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 1410.0
Subtracting 0 from 44 leaves us with 44.
Take the next digit (9) from the dividend and append it to 44, then repeat: 449 / 57

Advancing to step 6:
449 divided by 57 is 7 with a remainder of 50.
The next digit of our result is 7. 
Result so far: 14107.0
If we take 399 away from 449, we end up 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.

Moving on to step 7:
57 goes into 500 8 times with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 14107.8
Subtracting 456 from 500 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
57 can be fit into 440 7 times, resulting in a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 14107.87
If we take 399 away from 440, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
57 can be fit into 410 7 times, resulting in a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 14107.877
Subtracting 399 from 410 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 14107.877 with a remaining 0.0011.
