Let's divide 21166965 by 11
We want to divide 21166965 by 11.

Step 1:
When dividing 2 by 11, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 11

Advancing to step 2:
When dividing 21 by 11, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 11 from 21 to get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 11

Going ahead to step 3:
The number 11 fits into 101 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 2 after subtracting 99 from 101.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 11

Moving on to step 4:
11 goes into 26 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
Deduct 22 from 26 and we're left with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 11

Let's proceed to step 5:
11 goes into 46 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 1924.0
Subtract 44 from 46 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 11

Step 6:
If we divide 29 by 11, we get 2 and a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 19242.0
Subtract 22 from 29 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 11

Step 7:
11 goes into 76 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 192426.0
Subtracting 66 from 76 leaves us with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 11

Advancing to step 8:
11 can be fit into 105 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 1924269.0
Deduct 99 from 105 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 can be fit into 60 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 1924269.5
Deduct 55 from 60 and we're left 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.

Let's proceed to step 10:
11 can be fit into 50 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 1924269.54
If we take 44 away from 50, we end up 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.

Advancing to step 11:
11 goes into 60 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1924269.545
The remainder is 5 after subtracting 55 from 60.
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 12:
50 divided by 11 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1924269.5454
If we take 44 away from 50, we end up 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.

Step 13:
11 goes into 60 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1924269.54545
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.

On to step 14:
11 goes into 50 4 times with a remainder of 6.
The next digit of our result is 4. 
Result so far: 1924269.545454
Subtract 44 from 50 to 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.

Going ahead to step 15:
60 divided by 11 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1924269.5454545
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.

Advancing to step 16:
11 can be fit into 50 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1924269.54545454
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.

Our division results in 1924269.54545454 with a remaining 6e-09.
