Let's divide 827783 by 25
The aim is to understand the frequency of 25 in 827783.

Step 1:
8 divided by 25 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 25

Going ahead to step 2:
If we divide 82 by 25, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 7 after subtracting 75 from 82.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 25

Step 3:
If we divide 77 by 25, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtracting 75 from 77 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 25

On to step 4:
25 can be fit into 27 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 331.0
Subtract 25 from 27 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 25

Advancing to step 5:
If we divide 28 by 25, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 3311.0
Subtract 25 from 28 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 25

On to step 6:
If we divide 33 by 25, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 33111.0
Subtract 25 from 33 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
When dividing 80 by 25, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 33111.3
Subtract 75 from 80 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
If we divide 50 by 25, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 33111.32
The remainder is 0 after subtracting 50 from 50.
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 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 33111.32
Deduct 0 from 0 and we're left 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.

Let's proceed to step 10:
0 divided by 25 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33111.32
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.

Our division results in 33111.32 with a remaining 0.0.
