We're dividing 843143 by 11 
We want to divide 843143 by 11.

Let's proceed to step 1:
When dividing 8 by 11, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 11

Step 2:
The number 11 fits into 84 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 77 from 84, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 11

Advancing to step 3:
11 goes into 73 6 times with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtracting 66 from 73 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 11

Step 4:
11 can be fit into 71 6 times, resulting in a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 766.0
Deduct 66 from 71 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 11

Advancing to step 5:
11 goes into 54 4 times with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 7664.0
Subtracting 44 from 54 leaves us with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 11

Going ahead to step 6:
103 divided by 11 is 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 76649.0
If we take 99 away from 103, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
If we divide 40 by 11, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 76649.3
If we subtract 33 from 40, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
The number 11 fits into 70 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 76649.36
Subtracting 66 from 70 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 11 fits into 40 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 76649.363
Subtract 33 from 40 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
The number 11 fits into 70 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 76649.3636
If we take 66 away from 70, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
11 can be fit into 40 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 76649.36363
If we take 33 away from 40, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
11 goes into 70 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 76649.363636
Deduct 66 from 70 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
If we divide 40 by 11, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 76649.3636363
If we take 33 away from 40, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
70 divided by 11 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 76649.36363636
Deduct 66 from 70 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 76649.36363636, with a leftover of 4e-09.
