Let's divide 309402 by 11
Our goal is to divide 309402 by 11.

Moving on to step 1:
3 divided by 11 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 11

Moving on to step 2:
30 divided by 11 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 22 away from 30, we end up with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 11

Going ahead to step 3:
If we divide 89 by 11, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 88 from 89 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 11

Let's proceed to step 4:
The number 11 fits into 14 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 281.0
The remainder is 3 after subtracting 11 from 14.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 11

Let's proceed to step 5:
11 goes into 30 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2812.0
Subtract 22 from 30 to get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 11

Let's proceed to step 6:
If we divide 82 by 11, we get 7 and a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 28127.0
If we subtract 77 from 82, we 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.

Let's proceed to step 7:
11 goes into 50 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 28127.4
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.

Going ahead to step 8:
When dividing 60 by 11, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 28127.45
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.

Going ahead to step 9:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 28127.454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
60 divided by 11 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 28127.4545
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.

Advancing to step 11:
If we divide 50 by 11, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 28127.45454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
11 goes into 60 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 28127.454545
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.

Moving on to step 13:
When dividing 50 by 11, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 28127.4545454
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.

Advancing to step 14:
11 goes into 60 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 28127.45454545
If we subtract 55 from 60, we 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.

Our division results in 28127.45454545 with a remaining 5e-09.
