We look at the division of 480813 by 3 
We want to divide 480813 by 3.

Let's proceed to step 1:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 3 away from 4, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 3

On to step 2:
When dividing 18 by 3, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 18 from 18 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Moving on to step 3:
When dividing 0 by 3, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
Deduct 0 from 0 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 3

Advancing to step 4:
8 divided by 3 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 1602.0
If we take 6 away from 8, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 3

Step 5:
3 goes into 21 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 16027.0
Subtract 21 from 21 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

Step 6:
3 goes into 3 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 160271.0
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.

Advancing to step 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 160271.0
If we take 0 away from 0, 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.

On to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 160271.0
If we take 0 away from 0, 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.

The final outcome is 160271.0, with a leftover of 0.0.
