904604 divided by 9 
We're looking to find how many times 9 goes into 904604.

Step 1:
If we divide 9 by 9, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 9 from 9 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 9

Step 2:
0 divided by 9 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 9

Going ahead to step 3:
If we divide 4 by 9, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtract 0 from 4 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 9

Going ahead to step 4:
9 goes into 46 5 times with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 1005.0
If we subtract 45 from 46, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 9

Let's proceed to step 5:
9 can be fit into 10 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 10051.0
If we subtract 9 from 10, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 9

Moving on to step 6:
14 divided by 9 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 100511.0
Subtract 9 from 14 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 9 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 100511.5
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
When dividing 50 by 9, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 100511.55
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 100511.55, with a leftover of 0.005.
