We're dividing 904804 by 3 
Let's see how many times 3 fits into 904804.

Moving on to step 1:
3 can be fit into 9 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 9 from 9 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Going ahead to step 2:
When dividing 0 by 3, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 30.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 3

Let's proceed to step 3:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 301.0
If we take 3 away from 4, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 3

On to step 4:
18 divided by 3 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 3016.0
If we subtract 18 from 18, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Advancing to step 5:
When dividing 0 by 3, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30160.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Advancing to step 6:
4 divided by 3 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 301601.0
The remainder is 1 after subtracting 3 from 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 301601.3
Subtracting 9 from 10 leaves us 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.

Step 8:
3 goes into 10 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 301601.33
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 301601.33 with a remaining 0.001.
