We're dividing 256326 by 20 
We want to divide 256326 by 20.

On to step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 20

On to step 2:
If we divide 25 by 20, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 20 from 25 and we're left with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 20

Going ahead to step 3:
The number 20 fits into 56 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 40 from 56 to get 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 20

Advancing to step 4:
20 can be fit into 163 8 times, resulting in a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 128.0
Subtract 160 from 163 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 20

Going ahead to step 5:
32 divided by 20 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1281.0
Subtract 20 from 32 to get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 20

Let's proceed to step 6:
126 divided by 20 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 12816.0
Deduct 120 from 126 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
20 can be fit into 60 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 12816.3
If we subtract 60 from 60, 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.

Let's proceed to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12816.3
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.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12816.3
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 outcome is 12816.3, with a leftover of 0.0.
