We divide 829115 by 25
The aim is to understand the frequency of 25 in 829115.

Moving on to step 1:
8 divided by 25 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 25

Let's proceed to step 2:
25 goes into 82 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 75 from 82 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 25

Advancing to step 3:
The number 25 fits into 79 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 33.0
If we subtract 75 from 79, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 25

On to step 4:
The number 25 fits into 41 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 331.0
Subtract 25 from 41 to get 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 25

Advancing to step 5:
If we divide 161 by 25, we get 6 and a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 3316.0
The remainder is 11 after subtracting 150 from 161.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 25

Step 6:
When dividing 115 by 25, we get 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 33164.0
If we take 100 away from 115, 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.

On to step 7:
The number 25 fits into 150 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 33164.6
The remainder is 0 after subtracting 150 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 33164.6
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.

On to step 9:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 33164.6
If we subtract 0 from 0, 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.

Our division results in 33164.6 with a remaining 0.0.
