We divide 765523 by 25
The aim is to understand the frequency of 25 in 765523.

Moving on to step 1:
When dividing 7 by 25, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 25

On to step 2:
The number 25 fits into 76 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
If we take 75 away from 76, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 25

Advancing to step 3:
25 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we subtract 0 from 15, we get 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 25

Let's proceed to step 4:
If we divide 155 by 25, we get 6 and a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 306.0
Subtract 150 from 155 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 25

Let's proceed to step 5:
25 can be fit into 52 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 3062.0
Subtract 50 from 52 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 25

Moving on to step 6:
When dividing 23 by 25, we get 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 30620.0
Subtract 0 from 23 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
The number 25 fits into 230 9 times, leaving a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 30620.9
Subtract 225 from 230 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.

Going ahead to step 8:
25 can be fit into 50 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 30620.92
If we take 50 away from 50, 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.

Let's proceed to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30620.92
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.

Advancing to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30620.92
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.

The quotient of the division is 30620.92, and the remainder is 0.0.
