Let's divide 904408 by 3
Our goal is to divide 904408 by 3.

On to step 1:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Step 2:
3 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 0, we get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 3

Let's proceed to step 3:
3 can be fit into 4 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 301.0
Subtract 3 from 4 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

Let's proceed to step 4:
If we divide 14 by 3, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 3014.0
The remainder is 2 after subtracting 12 from 14.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

On to step 5:
3 goes into 20 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 30146.0
Subtracting 18 from 20 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

Advancing to step 6:
If we divide 28 by 3, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 301469.0
The remainder is 1 after subtracting 27 from 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 301469.3
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:
10 divided by 3 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 301469.33
Deduct 9 from 10 and we're left 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.

After the division, we end up with 301469.33 and a remainder of 0.001.
