We're dividing 57128887 by 254 
The aim is to understand the frequency of 254 in 57128887.

Going ahead to step 1:
The number 254 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 254

Going ahead to step 2:
254 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 254

On to step 3:
The number 254 fits into 571 2 times, leaving a remainder of 63.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 508 away from 571, we end up with 63.
Fetch the next digit (2) from the dividend, attach it to 63 and continue: 632 / 254

Let's proceed to step 4:
If we divide 632 by 254, we get 2 and a remainder of 124.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 508 from 632, we get 124.
Grab the next digit (8) from the dividend, add it to 124, then carry on: 1248 / 254

Step 5:
The number 254 fits into 1248 4 times, leaving a remainder of 232.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
Subtracting 1016 from 1248 leaves us with 232.
Fetch the next digit (8) from the dividend, attach it to 232 and continue: 2328 / 254

Going ahead to step 6:
254 can be fit into 2328 9 times, resulting in a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 2249.0
Subtracting 2286 from 2328 leaves us with 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 254

On to step 7:
428 divided by 254 is 1 with a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 22491.0
The remainder is 174 after subtracting 254 from 428.
Fetch the next digit (7) from the dividend, attach it to 174 and continue: 1747 / 254

Moving on to step 8:
1747 divided by 254 is 6 with a remainder of 223.
Record the quotient 6 as the next digit in the result. 
Result so far: 224916.0
If we subtract 1524 from 1747, we get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 9:
254 can be fit into 2230 8 times, resulting in a remainder of 198.
Record the quotient 8 as the next digit in the result. 
Result so far: 224916.8
The remainder is 198 after subtracting 2032 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 10:
254 goes into 1980 7 times with a remainder of 202.
The next digit of our result is 7. 
Result so far: 224916.87
Subtracting 1778 from 1980 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 11:
2020 divided by 254 is 7 with a remainder of 242.
The next digit of our result is 7. 
Result so far: 224916.877
If we subtract 1778 from 2020, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

After the division, we end up with 224916.877 and a remainder of 0.0242.
