We look at the division of 480373 by 1 
Let's see how many times 1 fits into 480373.

On to step 1:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 4 from 4, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Going ahead to step 2:
8 divided by 1 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Deduct 8 from 8 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Going ahead to step 3:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 480.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Advancing to step 4:
If we divide 3 by 1, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 4803.0
If we subtract 3 from 3, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Moving on to step 5:
If we divide 7 by 1, we get 7 and a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 48037.0
Subtracting 7 from 7 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Advancing to step 6:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 480373.0
If we take 3 away from 3, we end up 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 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 480373.0
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.

Step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 480373.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 480373.0 with a balance of 0.0.
