404504 divided by 3 
Let's see how many times 3 fits into 404504.

Step 1:
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: 1.0
If we take 3 away from 4, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

On to step 2:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 9 from 10 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

On to step 3:
The number 3 fits into 14 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 134.0
The remainder is 2 after subtracting 12 from 14.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Step 4:
3 can be fit into 25 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 1348.0
If we take 24 away from 25, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

On to step 5:
3 goes into 10 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 13483.0
Subtract 9 from 10 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

Moving on to step 6:
The number 3 fits into 14 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 134834.0
If we subtract 12 from 14, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 134834.6
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
3 goes into 20 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 134834.66
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 134834.66 with a balance of 0.002.
