Let's divide 480403 by 9
Our goal is to divide 480403 by 9.

On to step 1:
When dividing 4 by 9, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 9

Going ahead to step 2:
When dividing 48 by 9, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 45 from 48 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 9

Step 3:
When dividing 30 by 9, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we subtract 27 from 30, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 9

On to step 4:
When dividing 34 by 9, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 533.0
If we take 27 away from 34, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 9

Let's proceed to step 5:
The number 9 fits into 70 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 5337.0
If we subtract 63 from 70, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 9

Advancing to step 6:
The number 9 fits into 73 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 53378.0
If we subtract 72 from 73, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
9 goes into 10 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 53378.1
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.

On to step 8:
When dividing 10 by 9, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 53378.11
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 53378.11 with a remainder of 0.001.
