863933 ÷ 11 
Let's see how many times 11 fits into 863933.

Going ahead to step 1:
11 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 11

On to step 2:
11 can be fit into 86 7 times, resulting in a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 77 from 86 leaves us with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 11

Moving on to step 3:
If we divide 93 by 11, we get 8 and a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 78.0
Deduct 88 from 93 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 11

Going ahead to step 4:
The number 11 fits into 59 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 785.0
If we subtract 55 from 59, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 11

Advancing to step 5:
When dividing 43 by 11, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 7853.0
Deduct 33 from 43 and we're left with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 11

On to step 6:
The number 11 fits into 103 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 78539.0
The remainder is 4 after subtracting 99 from 103.
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 7:
40 divided by 11 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 78539.3
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.

Step 8:
11 can be fit into 70 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 78539.36
The remainder is 4 after subtracting 66 from 70.
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 9:
If we divide 40 by 11, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 78539.363
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.

Going ahead to step 10:
11 can be fit into 70 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 78539.3636
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.

Step 11:
11 can be fit into 40 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 78539.36363
Subtracting 33 from 40 leaves us 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.

On to step 12:
70 divided by 11 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 78539.363636
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.

On to step 13:
When dividing 40 by 11, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 78539.3636363
The remainder is 7 after subtracting 33 from 40.
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 14:
When dividing 70 by 11, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 78539.36363636
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 result is 78539.36363636 with a remainder of 4e-09.
