We're dividing 256950 by 20 
Our goal is to divide 256950 by 20.

Going ahead to 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
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 20

Advancing to step 2:
20 can be fit into 25 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 20 away from 25, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 20

On to step 3:
If we divide 56 by 20, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 40 from 56 and we're left with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 20

On to step 4:
When dividing 169 by 20, we get 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 128.0
If we take 160 away from 169, we end up with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 20

Let's proceed to step 5:
20 goes into 95 4 times with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 1284.0
Subtracting 80 from 95 leaves us with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 20

On to step 6:
If we divide 150 by 20, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 12847.0
If we take 140 away from 150, we end up 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.

Step 7:
When dividing 100 by 20, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12847.5
The remainder is 0 after subtracting 100 from 100.
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 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12847.5
If we take 0 away from 0, 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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12847.5
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.

The final result is 12847.5 with a remainder of 0.0.
