We divide 91304 by 20
We're looking to find how many times 20 goes into 91304.

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
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 20

Let's proceed to step 2:
If we divide 91 by 20, we get 4 and a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 80 from 91 and we're left with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 20

Let's proceed to step 3:
When dividing 113 by 20, we get 5 with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we subtract 100 from 113, we get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 20

On to step 4:
If we divide 130 by 20, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 456.0
The remainder is 10 after subtracting 120 from 130.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 20

Moving on to step 5:
104 divided by 20 is 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 4565.0
Subtract 100 from 104 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 6:
20 can be fit into 40 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 4565.2
Subtracting 40 from 40 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.

Advancing to step 7:
20 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: 4565.2
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.

Moving on to step 8:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4565.2
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 result is 4565.2 with a remainder of 0.0.
