341099 divided by 25 
The aim is to understand the frequency of 25 in 341099.

Let's proceed to step 1:
3 divided by 25 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 25

Let's proceed to step 2:
25 goes into 34 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 9 after subtracting 25 from 34.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 25

Moving on to step 3:
When dividing 91 by 25, we get 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 75 from 91 and we're left with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 25

Going ahead to step 4:
160 divided by 25 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
If we subtract 150 from 160, we get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 25

Going ahead to step 5:
The number 25 fits into 109 4 times, leaving a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 1364.0
Subtracting 100 from 109 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 25

Advancing to step 6:
When dividing 99 by 25, we get 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 13643.0
If we take 75 away from 99, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
240 divided by 25 is 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 13643.9
If we take 225 away from 240, we end up 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.

Step 8:
If we divide 150 by 25, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 13643.96
If we subtract 150 from 150, we 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.

Step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13643.96
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13643.96
If we take 0 away from 0, we end up 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.

After the division, we end up with 13643.96 and a remainder of 0.0.
