Let's divide 529391 by 20
We're looking to find how many times 20 goes into 529391.

Advancing to step 1:
5 divided by 20 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 20

On to step 2:
52 divided by 20 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 12 after subtracting 40 from 52.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 20

Let's proceed to step 3:
When dividing 129 by 20, we get 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 120 from 129 leaves us with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 20

Let's proceed to step 4:
20 can be fit into 93 4 times, resulting in a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 264.0
If we subtract 80 from 93, we get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 20

Step 5:
139 divided by 20 is 6 with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 2646.0
If we subtract 120 from 139, we get 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 20

Let's proceed to step 6:
191 divided by 20 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 26469.0
If we subtract 180 from 191, we 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.

Moving on to step 7:
If we divide 110 by 20, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 26469.5
If we take 100 away from 110, we end up 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.

Let's proceed to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 26469.55
If we subtract 100 from 100, we 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.

After the division, we end up with 26469.55 and a remainder of 0.0.
