20091 divided by 11 
Let's see how many times 11 fits into 20091.

Going ahead to step 1:
11 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 11

Step 2:
20 divided by 11 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 11 from 20 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 11

Moving on to step 3:
If we divide 90 by 11, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 88 from 90 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 11

Advancing to step 4:
If we divide 29 by 11, we get 2 and a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 182.0
If we take 22 away from 29, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 11

Moving on to step 5:
11 can be fit into 71 6 times, resulting in a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 1826.0
If we take 66 away from 71, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 6:
When dividing 50 by 11, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1826.4
Subtracting 44 from 50 leaves us 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.

Going ahead to step 7:
If we divide 60 by 11, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1826.45
If we subtract 55 from 60, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
11 can be fit into 50 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1826.454
Deduct 44 from 50 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.

Going ahead to step 9:
11 goes into 60 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 1826.4545
If we take 55 away from 60, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
11 can be fit into 50 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1826.45454
If we subtract 44 from 50, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
When dividing 60 by 11, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 1826.454545
Subtracting 55 from 60 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
When dividing 50 by 11, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 1826.4545454
Subtracting 44 from 50 leaves us 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 13:
When dividing 60 by 11, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1826.45454545
Subtract 55 from 60 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 1826.45454545 and a remainder of 5e-09.
