We look at the division of 804045 by 9 
We're looking to find how many times 9 goes into 804045.

Advancing to step 1:
9 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 9

On to step 2:
9 can be fit into 80 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 72 away from 80, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 9

Step 3:
9 goes into 84 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
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

Going ahead to step 4:
When dividing 30 by 9, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 893.0
The remainder is 3 after subtracting 27 from 30.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 9

Advancing to step 5:
When dividing 34 by 9, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 8933.0
Subtract 27 from 34 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 9

Going ahead to step 6:
75 divided by 9 is 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 89338.0
If we subtract 72 from 75, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
9 goes into 30 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 89338.3
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
9 goes into 30 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 89338.33
If we subtract 27 from 30, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 89338.33, with a leftover of 0.003.
