306707 divided by 25 
The aim is to understand the frequency of 25 in 306707.

Let's proceed to step 1:
The number 25 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 25

Advancing to step 2:
25 can be fit into 30 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 25 from 30, we get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 25

Moving on to step 3:
25 can be fit into 56 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 50 from 56 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 25

Going ahead to step 4:
If we divide 67 by 25, we get 2 and a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
If we subtract 50 from 67, we get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 25

Going ahead to step 5:
The number 25 fits into 170 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 1226.0
The remainder is 20 after subtracting 150 from 170.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 25

Advancing to step 6:
If we divide 207 by 25, we get 8 and a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 12268.0
Subtract 200 from 207 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 25 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 12268.2
The remainder is 20 after subtracting 50 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
If we divide 200 by 25, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 12268.28
Subtract 200 from 200 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.
Put 0 as the next digit of the answer. 
Result so far: 12268.28
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.

On to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12268.28
Subtracting 0 from 0 leaves us 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 final outcome is 12268.28, with a leftover of 0.0.
