25866711 ÷ 254 
The aim is to understand the frequency of 254 in 25866711.

Moving on to step 1:
When dividing 2 by 254, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 254

Let's proceed to step 2:
254 goes into 25 0 times with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 254

On to step 3:
When dividing 258 by 254, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 254 from 258 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 254

On to step 4:
46 divided by 254 is 0 with a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 46 leaves us with 46.
Append the next digit (6) from the dividend to 46 and continue with: 466 / 254

Moving on to step 5:
254 can be fit into 466 1 times, resulting in a remainder of 212.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Deduct 254 from 466 and we're left with 212.
Append the next digit (7) from the dividend to 212 and continue with: 2127 / 254

Let's proceed to step 6:
The number 254 fits into 2127 8 times, leaving a remainder of 95.
Record the quotient 8 as the next digit in the result. 
Result so far: 1018.0
Subtract 2032 from 2127 to get 95.
Bring next digit (1) of the dividend behind the 95 and repeat the process: 951 / 254

On to step 7:
The number 254 fits into 951 3 times, leaving a remainder of 189.
Write down 3 as next digit of the result. 
Result so far: 10183.0
The remainder is 189 after subtracting 762 from 951.
Append the next digit (1) from the dividend to 189 and continue with: 1891 / 254

Moving on to step 8:
1891 divided by 254 is 7 with a remainder of 113.
The next digit of our result is 7. 
Result so far: 101837.0
Deduct 1778 from 1891 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 9:
1130 divided by 254 is 4 with a remainder of 114.
The number 4 becomes the next digit in our result. 
Result so far: 101837.4
If we subtract 1016 from 1130, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 10:
254 goes into 1140 4 times with a remainder of 124.
Use 4 as the next digit of our solution. 
Result so far: 101837.44
If we take 1016 away from 1140, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Our division results in 101837.44 with a remaining 0.124.
