25128335 divided by 154 
The aim is to understand the frequency of 154 in 25128335.

Moving on to step 1:
The number 154 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 154

On to step 2:
154 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 154

Let's proceed to step 3:
154 goes into 251 1 times with a remainder of 97.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 154 away from 251, we end up with 97.
Append the next digit (2) from the dividend to 97 and continue with: 972 / 154

Let's proceed to step 4:
154 goes into 972 6 times with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 924 from 972 to get 48.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 154

Moving on to step 5:
488 divided by 154 is 3 with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 163.0
If we take 462 away from 488, we end up with 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 154

Advancing to step 6:
263 divided by 154 is 1 with a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 1631.0
Subtract 154 from 263 to get 109.
Fetch the next digit (3) from the dividend, attach it to 109 and continue: 1093 / 154

Let's proceed to step 7:
154 goes into 1093 7 times with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 16317.0
If we take 1078 away from 1093, we end up with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 154

Advancing to step 8:
When dividing 155 by 154, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 163171.0
Subtracting 154 from 155 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
10 divided by 154 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 163171.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
154 goes into 100 0 times with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 163171.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 163171.0 with a remaining 0.1.
