Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 10 after subtracting 11 from 21.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 11

Moving on to step 3:
103 divided by 11 is 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 99 away from 103, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 11

Advancing to step 4:
45 divided by 11 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 194.0
The remainder is 1 after subtracting 44 from 45.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 11

Going ahead to step 5:
19 divided by 11 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1941.0
Deduct 11 from 19 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 11

Let's proceed to step 6:
11 can be fit into 84 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 19417.0
The remainder is 7 after subtracting 77 from 84.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 11

Step 7:
11 can be fit into 73 6 times, resulting in a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 194176.0
If we take 66 away from 73, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 11

Step 8:
The number 11 fits into 78 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 1941767.0
Deduct 77 from 78 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
10 divided by 11 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1941767.0
Subtracting 0 from 10 leaves us 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.

Let's proceed to step 10:
100 divided by 11 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1941767.09
Subtracting 99 from 100 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
The number 11 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 1941767.09
If we take 0 away from 10, we end up 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.

Step 12:
The number 11 fits into 100 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1941767.0909
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
11 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1941767.0909
Subtracting 0 from 10 leaves us 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.

Step 14:
When dividing 100 by 11, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1941767.090909
Subtracting 99 from 100 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 15:
11 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1941767.090909
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 16:
11 goes into 100 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1941767.09090909
The remainder is 1 after subtracting 99 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.
