813842 divided by 9 
We want to divide 813842 by 9.

Going ahead to step 1:
The number 9 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.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 9

On to step 2:
When dividing 81 by 9, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 0 after subtracting 81 from 81.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 9

On to step 3:
3 divided by 9 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 9

Step 4:
38 divided by 9 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 904.0
If we take 36 away from 38, we end up with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 9

Advancing to step 5:
9 goes into 24 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 9042.0
Deduct 18 from 24 and we're left with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 9

Let's proceed to step 6:
9 goes into 62 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 90426.0
Deduct 54 from 62 and we're left with 8.
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 7:
9 can be fit into 80 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 90426.8
Subtracting 72 from 80 leaves us with 8.
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 8:
9 can be fit into 80 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 90426.88
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 90426.88, with a leftover of 0.008.
