990838 divided by 6 
We're looking to find how many times 6 goes into 990838.

Advancing to step 1:
6 can be fit into 9 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 6 from 9 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 6

Moving on to step 2:
When dividing 39 by 6, we get 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 3 after subtracting 36 from 39.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 6

On to step 3:
If we divide 30 by 6, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 165.0
Subtracting 30 from 30 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 6

Advancing to step 4:
If we divide 8 by 6, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1651.0
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

Let's proceed to step 5:
6 goes into 23 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 16513.0
If we take 18 away from 23, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 6

Going ahead to step 6:
The number 6 fits into 58 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 165139.0
Subtracting 54 from 58 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 7:
40 divided by 6 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 165139.6
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.

Let's proceed to step 8:
6 goes into 40 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 165139.66
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 165139.66 with a remaining 0.004.
