25041566 divided by 236 
The aim is to understand the frequency of 236 in 25041566.

Advancing to step 1:
If we divide 2 by 236, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 236

Let's proceed to step 2:
236 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 236

Going ahead to step 3:
250 divided by 236 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 236 from 250 to get 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 236

On to step 4:
144 divided by 236 is 0 with a remainder of 144.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 144 and we're left with 144.
Grab the next digit (1) from the dividend, add it to 144, then carry on: 1441 / 236

Going ahead to step 5:
The number 236 fits into 1441 6 times, leaving a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Subtracting 1416 from 1441 leaves us with 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 236

Going ahead to step 6:
236 goes into 255 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1061.0
If we take 236 away from 255, we end up with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 236

Moving on to step 7:
If we divide 196 by 236, we get 0 and a remainder of 196.
Use 0 as the next digit of our solution. 
Result so far: 10610.0
Deduct 0 from 196 and we're left with 196.
Grab the next digit (6) from the dividend, add it to 196, then carry on: 1966 / 236

Step 8:
The number 236 fits into 1966 8 times, leaving a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 106108.0
Subtract 1888 from 1966 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
236 goes into 780 3 times with a remainder of 72.
The number 3 becomes the next digit in our result. 
Result so far: 106108.3
Deduct 708 from 780 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
236 can be fit into 720 3 times, resulting in a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 106108.33
Subtracting 708 from 720 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 106108.33, and the remainder is 0.012.
