220393 ÷ 20 
We want to divide 220393 by 20.

Going ahead to step 1:
20 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 20

Going ahead to step 2:
20 can be fit into 22 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 20 from 22 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 20

Let's proceed to step 3:
20 can be fit into 20 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 20 from 20 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 20

Going ahead to step 4:
20 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 20

Going ahead to step 5:
39 divided by 20 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1101.0
Subtract 20 from 39 to get 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 20

On to step 6:
The number 20 fits into 193 9 times, leaving a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 11019.0
Subtract 180 from 193 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
130 divided by 20 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 11019.6
If we subtract 120 from 130, we 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.

On to step 8:
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: 11019.65
If we take 100 away from 100, 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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 11019.65
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.

On to step 10:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11019.65
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.

After the division, we end up with 11019.65 and a remainder of 0.0.
