Let's divide 303139 by 11
We want to figure out the number of times 303139 can be divided by 11.

Let's proceed to step 1:
11 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 11

Advancing to step 2:
30 divided by 11 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 8 after subtracting 22 from 30.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 11

Moving on to step 3:
11 can be fit into 83 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 27.0
If we subtract 77 from 83, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 11

Going ahead to step 4:
11 can be fit into 61 5 times, resulting in a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 275.0
Deduct 55 from 61 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 11

Let's proceed to step 5:
11 can be fit into 63 5 times, resulting in a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 2755.0
The remainder is 8 after subtracting 55 from 63.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 11

Going ahead to step 6:
When dividing 89 by 11, we get 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 27558.0
If we subtract 88 from 89, 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.

Advancing to step 7:
The number 11 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 27558.0
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.

Moving on to step 8:
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: 27558.09
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.

Advancing to step 9:
10 divided by 11 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 27558.09
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.

Advancing to step 10:
11 goes into 100 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 27558.0909
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:
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: 27558.0909
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.

Going ahead to step 12:
When dividing 100 by 11, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 27558.090909
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.

Advancing to step 13:
10 divided by 11 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 27558.090909
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.

Going ahead to step 14:
100 divided by 11 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 27558.09090909
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.

The final result is 27558.09090909 with a remainder of 1e-09.
