We're dividing 403480 by 10 
We want to figure out the number of times 403480 can be divided by 10.

Moving on to step 1:
The number 10 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 10

Moving on to step 2:
The number 10 fits into 40 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 40 from 40 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 10

Moving on to step 3:
3 divided by 10 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 10

Going ahead to step 4:
When dividing 34 by 10, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 403.0
Subtract 30 from 34 to get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 10

Step 5:
48 divided by 10 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4034.0
If we take 40 away from 48, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 10

On to step 6:
When dividing 80 by 10, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 40348.0
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40348.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40348.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 40348.0, and the remainder is 0.0.
