We're dividing 523490 by 20 
Our goal is to divide 523490 by 20.

Let's proceed to step 1:
If we divide 5 by 20, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 20

Moving on to step 2:
20 goes into 52 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 40 from 52 to get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 20

Going ahead to step 3:
20 can be fit into 123 6 times, resulting in a remainder of 3.
The next digit of our result is 6. 
Result so far: 26.0
If we take 120 away from 123, we end up with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 20

Moving on to step 4:
20 goes into 34 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 261.0
Subtracting 20 from 34 leaves us with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 20

Step 5:
149 divided by 20 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 2617.0
If we subtract 140 from 149, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 20

Going ahead to step 6:
If we divide 90 by 20, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 26174.0
If we take 80 away from 90, 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.

Moving on to step 7:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 26174.5
Subtract 100 from 100 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.

Let's proceed to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 26174.5
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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 26174.5
If we subtract 0 from 0, 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.

The final result is 26174.5 with a remainder of 0.0.
