Let's divide 840631 by 9
We're looking to find how many times 9 goes into 840631.

Moving on to step 1:
If we divide 8 by 9, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 9

Step 2:
When dividing 84 by 9, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 81 from 84 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 9

On to step 3:
If we divide 30 by 9, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtracting 27 from 30 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 9

Moving on to step 4:
9 can be fit into 36 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 934.0
Subtracting 36 from 36 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 9

Moving on to step 5:
3 divided by 9 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 9340.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 9

Moving on to step 6:
If we divide 31 by 9, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 93403.0
If we subtract 27 from 31, 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.

On to step 7:
9 goes into 40 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 93403.4
Deduct 36 from 40 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 8:
The number 9 fits into 40 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 93403.44
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.

In conclusion, the division gives 93403.44 with a balance of 0.004.
