804403 ÷ 9 
We want to divide 804403 by 9.

Going ahead to step 1:
9 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 9

Moving on to step 2:
If we divide 80 by 9, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 72 from 80 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 9

Going ahead to 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
Subtracting 81 from 84 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 9

Advancing to step 4:
The number 9 fits into 34 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 893.0
If we subtract 27 from 34, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 9

Going ahead to step 5:
9 goes into 70 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 8937.0
If we take 63 away from 70, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 9

Moving on to step 6:
When dividing 73 by 9, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 89378.0
The remainder is 1 after subtracting 72 from 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 9 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 89378.1
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
The number 9 fits into 10 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 89378.11
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 89378.11, with a leftover of 0.001.
