913191 ÷ 20 
Our goal is to divide 913191 by 20.

On to step 1:
When dividing 9 by 20, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 20

Moving on to step 2:
91 divided by 20 is 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
If we take 80 away from 91, we end up with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 20

Moving on to step 3:
If we divide 113 by 20, we get 5 and a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtracting 100 from 113 leaves us with 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 20

Let's proceed to step 4:
When dividing 131 by 20, we get 6 with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 456.0
Subtract 120 from 131 to get 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 20

Advancing to step 5:
119 divided by 20 is 5 with a remainder of 19.
The next digit of our result is 5. 
Result so far: 4565.0
The remainder is 19 after subtracting 100 from 119.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 20

Moving on to step 6:
191 divided by 20 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 45659.0
Subtract 180 from 191 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
20 can be fit into 110 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 45659.5
The remainder is 10 after subtracting 100 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 45659.55
The remainder is 0 after subtracting 100 from 100.
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 45659.55 with a remainder of 0.0.
