We divide 249571 by 20
Our goal is to divide 249571 by 20.

Step 1:
When dividing 2 by 20, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 20

Step 2:
20 can be fit into 24 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 4 after subtracting 20 from 24.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 20

Going ahead to step 3:
20 can be fit into 49 2 times, resulting in a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 9 after subtracting 40 from 49.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 20

Going ahead to step 4:
20 can be fit into 95 4 times, resulting in a remainder of 15.
The next digit of our result is 4. 
Result so far: 124.0
The remainder is 15 after subtracting 80 from 95.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 20

Let's proceed to step 5:
When dividing 157 by 20, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 1247.0
If we subtract 140 from 157, we get 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 20

Moving on to step 6:
If we divide 171 by 20, we get 8 and a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 12478.0
If we take 160 away from 171, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 20 fits into 110 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 12478.5
Subtracting 100 from 110 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 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 12478.55
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.

In conclusion, the division gives 12478.55 with a balance of 0.0.
