631863 ÷ 25 
The aim is to understand the frequency of 25 in 631863.

Advancing to step 1:
6 divided by 25 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 25

Step 2:
When dividing 63 by 25, we get 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 50 from 63 and we're left with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 25

Going ahead to step 3:
The number 25 fits into 131 5 times, leaving a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 125 from 131, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 25

On to step 4:
When dividing 68 by 25, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
If we take 50 away from 68, we end up with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 25

Moving on to step 5:
25 can be fit into 186 7 times, resulting in a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 2527.0
Deduct 175 from 186 and we're left with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 25

Moving on to step 6:
When dividing 113 by 25, we get 4 with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 25274.0
The remainder is 13 after subtracting 100 from 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
The number 25 fits into 130 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 25274.5
Deduct 125 from 130 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
50 divided by 25 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 25274.52
Subtracting 50 from 50 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.

Step 9:
25 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25274.52
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.

Moving on to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25274.52
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.

In conclusion, the division gives 25274.52 with a balance of 0.0.
