Let's divide 249872 by 20
We want to divide 249872 by 20.

Let's proceed to step 1:
When dividing 2 by 20, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 20

Going ahead to step 2:
20 can be fit into 24 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 20 from 24.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 20

On to step 3:
When dividing 49 by 20, we get 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 40 from 49 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 20

Step 4:
98 divided by 20 is 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 124.0
If we take 80 away from 98, we end up with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 20

Moving on to step 5:
If we divide 187 by 20, we get 9 and a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 1249.0
Subtract 180 from 187 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 20

Advancing to step 6:
The number 20 fits into 72 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 12493.0
Subtract 60 from 72 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
120 divided by 20 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 12493.6
If we take 120 away from 120, we end up 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.

Step 8:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12493.6
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:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12493.6
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.

The final result is 12493.6 with a remainder of 0.0.
