628106 divided by 25 
The aim is to understand the frequency of 25 in 628106.

Going ahead to step 1:
6 divided by 25 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 25

Moving on to step 2:
The number 25 fits into 62 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 12 after subtracting 50 from 62.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 25

On to step 3:
If we divide 128 by 25, we get 5 and a remainder of 3.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 125 from 128 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 25

Advancing to step 4:
The number 25 fits into 31 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 251.0
Subtract 25 from 31 to get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 25

Going ahead to step 5:
25 goes into 60 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2512.0
Deduct 50 from 60 and we're left with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 25

Step 6:
When dividing 106 by 25, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 25124.0
Deduct 100 from 106 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 25, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 25124.2
If we take 50 away from 60, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
25 goes into 100 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 25124.24
Subtract 100 from 100 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.

Step 9:
0 divided by 25 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25124.24
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.

Step 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 25124.24
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 25124.24 and a remainder of 0.0.
