We look at the division of 9480309 by 20 
Let's see how many times 20 fits into 9480309.

Step 1:
20 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 20

Step 2:
The number 20 fits into 94 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 80 from 94 to get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 20

Going ahead to step 3:
20 can be fit into 148 7 times, resulting in a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 47.0
The remainder is 8 after subtracting 140 from 148.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 20

Step 4:
20 goes into 80 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 474.0
The remainder is 0 after subtracting 80 from 80.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 20

Let's proceed to step 5:
If we divide 3 by 20, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 4740.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 20

Advancing to step 6:
20 can be fit into 30 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 47401.0
If we subtract 20 from 30, we get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 20

Going ahead to step 7:
If we divide 109 by 20, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 474015.0
Deduct 100 from 109 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
20 goes into 90 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 474015.4
Subtracting 80 from 90 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
When dividing 100 by 20, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 474015.45
If we take 100 away from 100, 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 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 474015.45
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.

Moving on to step 11:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 474015.45
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.

The final outcome is 474015.45, with a leftover of 0.0.
