We're dividing 623635 by 25 
Let's see how many times 25 fits into 623635.

Going ahead to step 1:
6 divided by 25 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 25

On to step 2:
When dividing 62 by 25, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 50 from 62 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 25

Let's proceed to step 3:
The number 25 fits into 123 4 times, leaving a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 24.0
Deduct 100 from 123 and we're left with 23.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 25

Going ahead to step 4:
If we divide 236 by 25, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 249.0
If we take 225 away from 236, we end up with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 25

Advancing to step 5:
113 divided by 25 is 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 2494.0
Deduct 100 from 113 and we're left with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 25

Advancing to step 6:
25 goes into 135 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 24945.0
If we take 125 away from 135, 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 7:
If we divide 100 by 25, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 24945.4
Subtracting 100 from 100 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 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 24945.4
Deduct 0 from 0 and we're left 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 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 24945.4
Deduct 0 from 0 and we're left 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.

After the division, we end up with 24945.4 and a remainder of 0.0.
