768713 ÷ 25 
The aim is to understand the frequency of 25 in 768713.

Going ahead to step 1:
The number 25 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 25

Advancing to step 2:
25 can be fit into 76 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 75 from 76 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 25

Moving on to step 3:
When dividing 18 by 25, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 25

On to step 4:
187 divided by 25 is 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 307.0
If we subtract 175 from 187, we get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 25

Let's proceed to step 5:
When dividing 121 by 25, we get 4 with a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 3074.0
Subtract 100 from 121 to get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 25

Step 6:
213 divided by 25 is 8 with a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 30748.0
Subtract 200 from 213 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
25 can be fit into 130 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 30748.5
Subtract 125 from 130 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.

Moving on to step 8:
When dividing 50 by 25, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 30748.52
Subtract 50 from 50 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:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30748.52
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.

Advancing to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30748.52
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.

Our division results in 30748.52 with a remaining 0.0.
