We're dividing 520635 by 25 
We're looking to find how many times 25 goes into 520635.

Let's proceed to step 1:
25 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 25

On to step 2:
When dividing 52 by 25, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 2 after subtracting 50 from 52.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 25

Step 3:
25 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 25

On to step 4:
25 can be fit into 206 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 208.0
The remainder is 6 after subtracting 200 from 206.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 25

Step 5:
If we divide 63 by 25, we get 2 and a remainder of 13.
The next digit of our result is 2. 
Result so far: 2082.0
Subtracting 50 from 63 leaves us with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 25

Advancing to step 6:
When dividing 135 by 25, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 20825.0
Subtracting 125 from 135 leaves us 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.

Moving on to step 7:
If we divide 100 by 25, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 20825.4
If we subtract 100 from 100, 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.

Moving on to step 8:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 20825.4
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.

Moving on to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20825.4
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.

After the division, we end up with 20825.4 and a remainder of 0.0.
