40480 divided by 3 
We're looking to find how many times 3 goes into 40480.

Advancing to step 1:
If we divide 4 by 3, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

Advancing to step 2:
3 goes into 10 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 9 from 10, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

Going ahead to step 3:
3 goes into 14 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 134.0
If we take 12 away from 14, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Step 4:
When dividing 28 by 3, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 1349.0
If we subtract 27 from 28, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 3

On to step 5:
When dividing 10 by 3, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 13493.0
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.

Advancing to step 6:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 13493.3
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.

Let's proceed to step 7:
3 goes into 10 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 13493.33
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.

In conclusion, the division gives 13493.33 with a balance of 0.001.
