We look at the division of 213780 by 20 
Let's see how many times 20 fits into 213780.

Step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 20

On to step 2:
21 divided by 20 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 20 away from 21, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 20

Advancing to step 3:
13 divided by 20 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 20

Going ahead to step 4:
20 can be fit into 137 6 times, resulting in a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
The remainder is 17 after subtracting 120 from 137.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 20

Advancing to step 5:
If we divide 178 by 20, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 1068.0
Deduct 160 from 178 and we're left with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 20

Moving on to step 6:
20 goes into 180 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 10689.0
If we subtract 180 from 180, 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.

Moving on to step 7:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10689.0
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.

Advancing to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10689.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 10689.0 with a remaining 0.0.
