We're dividing 491072 by 20 
We're looking to find how many times 20 goes into 491072.

Advancing to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 20

Going ahead to step 2:
If we divide 49 by 20, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 40 from 49 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 20

Moving on to step 3:
20 can be fit into 91 4 times, resulting in a remainder of 11.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 80 from 91 to get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 20

Step 4:
110 divided by 20 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 245.0
The remainder is 10 after subtracting 100 from 110.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 20

Moving on to step 5:
When dividing 107 by 20, we get 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 2455.0
If we take 100 away from 107, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 20

Going ahead to step 6:
72 divided by 20 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 24553.0
If we take 60 away from 72, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
20 can be fit into 120 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 24553.6
Deduct 120 from 120 and we're left 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.

Going ahead to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24553.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 24553.6
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.

After the division, we end up with 24553.6 and a remainder of 0.0.
