25250 ÷ 20 
We're looking to find how many times 20 goes into 25250.

Step 1:
2 divided by 20 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 20

Going ahead to step 2:
When dividing 25 by 20, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 20 from 25 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 20

Advancing to step 3:
The number 20 fits into 52 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 12 after subtracting 40 from 52.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 20

Step 4:
The number 20 fits into 125 6 times, leaving a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
If we take 120 away from 125, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 20

Moving on to step 5:
When dividing 50 by 20, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 1262.0
Subtract 40 from 50 to get 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 6:
If we divide 100 by 20, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1262.5
Deduct 100 from 100 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.

Advancing to step 7:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1262.5
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.

Going ahead to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1262.5
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 1262.5 and a remainder of 0.0.
