21131274 divided by 11 
Let's see how many times 11 fits into 21131274.

Let's proceed to step 1:
11 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 11

Advancing to step 2:
11 can be fit into 21 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
If we take 11 away from 21, we end up with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 11

Moving on to step 3:
If we divide 101 by 11, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 99 from 101 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 11

Advancing to step 4:
11 goes into 23 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 192.0
The remainder is 1 after subtracting 22 from 23.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 11

Advancing to step 5:
The number 11 fits into 11 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1921.0
The remainder is 0 after subtracting 11 from 11.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 11

Step 6:
When dividing 2 by 11, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 19210.0
If we take 0 away from 2, we end up with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 11

Step 7:
27 divided by 11 is 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 192102.0
The remainder is 5 after subtracting 22 from 27.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 11

Going ahead to step 8:
When dividing 54 by 11, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 1921024.0
If we subtract 44 from 54, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
The number 11 fits into 100 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 1921024.9
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
If we divide 10 by 11, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1921024.9
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.

Going ahead to step 11:
100 divided by 11 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 1921024.909
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.

Going ahead to step 12:
11 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1921024.909
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 13:
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: 1921024.90909
If we take 99 away from 100, we end up 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.

Step 14:
11 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1921024.90909
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.

Going ahead to step 15:
11 can be fit into 100 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1921024.9090909
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.

Step 16:
10 divided by 11 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1921024.9090909
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 1921024.9090909 and a remainder of 1e-08.
