We're dividing 263815 by 6 
We're looking to find how many times 6 goes into 263815.

Let's proceed to step 1:
2 divided by 6 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 6

On to step 2:
If we divide 26 by 6, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 2 after subtracting 24 from 26.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 6

Going ahead to step 3:
When dividing 23 by 6, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we subtract 18 from 23, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 6

On to step 4:
When dividing 58 by 6, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 439.0
If we subtract 54 from 58, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 6

Moving on to step 5:
6 can be fit into 41 6 times, resulting in a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 4396.0
Subtract 36 from 41 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 6

Step 6:
6 goes into 55 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 43969.0
If we take 54 away from 55, we end up 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 7:
10 divided by 6 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 43969.1
If we subtract 6 from 10, we get 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 8:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 43969.16
Subtracting 36 from 40 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.

Step 9:
When dividing 40 by 6, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 43969.166
If we subtract 36 from 40, we get 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 43969.166 with a remainder of 0.0004.
