20853139 ÷ 11 
Our goal is to divide 20853139 by 11.

On to step 1:
11 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 11

On to step 2:
The number 11 fits into 20 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 11 from 20 leaves us with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 11

Let's proceed to step 3:
11 goes into 98 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 88 away from 98, we end up with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 11

Going ahead to step 4:
If we divide 105 by 11, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 189.0
If we take 99 away from 105, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 11

Going ahead to step 5:
63 divided by 11 is 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 1895.0
Subtracting 55 from 63 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 11

On to step 6:
81 divided by 11 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 18957.0
Subtracting 77 from 81 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 11

Step 7:
The number 11 fits into 43 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 189573.0
Subtract 33 from 43 to get 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 11

On to step 8:
11 can be fit into 109 9 times, resulting in a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 1895739.0
The remainder is 10 after subtracting 99 from 109.
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 9:
The number 11 fits into 100 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 1895739.9
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.

On to step 10:
The number 11 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1895739.9
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.

Let's proceed to step 11:
When dividing 100 by 11, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1895739.909
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.

Step 12:
If we divide 10 by 11, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1895739.909
Deduct 0 from 10 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.

On to step 13:
If we divide 100 by 11, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1895739.90909
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:
If we divide 10 by 11, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 1895739.90909
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 15:
When dividing 100 by 11, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 1895739.9090909
Subtract 99 from 100 to 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.

Moving on to step 16:
If we divide 10 by 11, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1895739.9090909
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.

The final outcome is 1895739.9090909, with a leftover of 1e-08.
