717634 divided by 25 
The aim is to understand the frequency of 25 in 717634.

Going ahead to step 1:
If we divide 7 by 25, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 25

On to step 2:
The number 25 fits into 71 2 times, leaving a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 21 after subtracting 50 from 71.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 25

Going ahead to step 3:
The number 25 fits into 217 8 times, leaving a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 200 from 217 and we're left with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 25

Step 4:
If we divide 176 by 25, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 287.0
If we take 175 away from 176, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 25

Moving on to step 5:
If we divide 13 by 25, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 2870.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 25

Moving on to step 6:
The number 25 fits into 134 5 times, leaving a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 28705.0
If we subtract 125 from 134, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
The number 25 fits into 90 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 28705.3
Subtracting 75 from 90 leaves us 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.

Advancing to step 8:
When dividing 150 by 25, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 28705.36
If we take 150 away from 150, 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.

On to step 9:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28705.36
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.

Let's proceed to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28705.36
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.

The quotient of the division is 28705.36, and the remainder is 0.0.
