We look at the division of 836503 by 6 
We're looking to find how many times 6 goes into 836503.

Going ahead to step 1:
6 can be fit into 8 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 2 after subtracting 6 from 8.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 6

Advancing to step 2:
The number 6 fits into 23 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 18 away from 23, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 6

Moving on to step 3:
If we divide 56 by 6, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Subtract 54 from 56 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 6

Step 4:
When dividing 25 by 6, we get 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 1394.0
If we take 24 away from 25, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 6

Moving on to step 5:
10 divided by 6 is 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 13941.0
Subtract 6 from 10 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 6

Moving on to step 6:
If we divide 43 by 6, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 139417.0
Subtract 42 from 43 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 6, we get 1 and a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 139417.1
Subtracting 6 from 10 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.

Moving on to step 8:
40 divided by 6 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 139417.16
Subtract 36 from 40 to 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.

Moving on to step 9:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 139417.166
If we take 36 away from 40, 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.

The final outcome is 139417.166, with a leftover of 0.0004.
