We're dividing 863831 by 13 
Let's see how many times 13 fits into 863831.

Step 1:
The number 13 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 13

Going ahead to step 2:
The number 13 fits into 86 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 78 from 86 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 13

Moving on to step 3:
When dividing 83 by 13, we get 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we subtract 78 from 83, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 13

Going ahead to step 4:
If we divide 58 by 13, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 664.0
Subtracting 52 from 58 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 13

Going ahead to step 5:
When dividing 63 by 13, we get 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 6644.0
If we take 52 away from 63, we end up with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 13

Moving on to step 6:
The number 13 fits into 111 8 times, leaving a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 66448.0
The remainder is 7 after subtracting 104 from 111.
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 7:
13 goes into 70 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 66448.5
Subtracting 65 from 70 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
If we divide 50 by 13, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 66448.53
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
110 divided by 13 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 66448.538
Subtract 104 from 110 to get 6.
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 10:
60 divided by 13 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 66448.5384
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 66448.53846
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
13 goes into 20 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 66448.538461
The remainder is 7 after subtracting 13 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
13 goes into 70 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 66448.5384615
Subtracting 65 from 70 leaves us with 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 14:
When dividing 50 by 13, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 66448.53846153
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 66448.53846153 with a remainder of 1.1e-08.
