636730 ÷ 25 
We're looking to find how many times 25 goes into 636730.

Going ahead to step 1:
When dividing 6 by 25, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 25

Let's proceed to step 2:
25 can be fit into 63 2 times, resulting in a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
If we take 50 away from 63, we end up with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 25

Let's proceed to step 3:
25 can be fit into 136 5 times, resulting in a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 125 from 136 to get 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 25

Going ahead to step 4:
25 can be fit into 117 4 times, resulting in a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 254.0
If we subtract 100 from 117, we get 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 25

Let's proceed to step 5:
If we divide 173 by 25, we get 6 and a remainder of 23.
The next digit of our result is 6. 
Result so far: 2546.0
The remainder is 23 after subtracting 150 from 173.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 25

Advancing to step 6:
When dividing 230 by 25, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 25469.0
Subtract 225 from 230 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
50 divided by 25 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 25469.2
Deduct 50 from 50 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.

Going ahead to step 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25469.2
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.

Going ahead to step 9:
25 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 25469.2
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.

Our division results in 25469.2 with a remaining 0.0.
