253444 ÷ 25 
The aim is to understand the frequency of 25 in 253444.

Moving on to step 1:
25 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 25

Advancing to step 2:
When dividing 25 by 25, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 25 from 25, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 25

Step 3:
25 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 25

On to step 4:
25 can be fit into 34 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtract 25 from 34 to get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 25

On to step 5:
The number 25 fits into 94 3 times, leaving a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 1013.0
If we take 75 away from 94, we end up with 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 25

Step 6:
25 goes into 194 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 10137.0
If we subtract 175 from 194, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 25 is 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 10137.7
Deduct 175 from 190 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
25 goes into 150 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 10137.76
Subtract 150 from 150 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10137.76
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10137.76
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 10137.76 with a remainder of 0.0.
