We divide 121111 by 20
We want to divide 121111 by 20.

Moving on to step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 20

Step 2:
20 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 20

Step 3:
20 can be fit into 121 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 120 from 121 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 20

Going ahead to step 4:
If we divide 11 by 20, we get 0 and a remainder of 11.
The next digit of our result is 0. 
Result so far: 60.0
Deduct 0 from 11 and we're left with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 20

Moving on to step 5:
111 divided by 20 is 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 605.0
If we subtract 100 from 111, we get 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 20

Let's proceed to step 6:
20 can be fit into 111 5 times, resulting in a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 6055.0
Deduct 100 from 111 and we're left 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.

On to step 7:
If we divide 110 by 20, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 6055.5
Deduct 100 from 110 and we're left 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.

Advancing to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6055.55
Deduct 100 from 100 and we're left 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.

After the division, we end up with 6055.55 and a remainder of 0.0.
