524859 ÷ 20 
We want to divide 524859 by 20.

Moving on to step 1:
If we divide 5 by 20, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 20

Let's proceed to step 2:
20 can be fit into 52 2 times, resulting in 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 (4) from the dividend after 12, then repeat: 124 / 20

Step 3:
When dividing 124 by 20, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtracting 120 from 124 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 20

Step 4:
If we divide 48 by 20, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 262.0
If we take 40 away from 48, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 20

Going ahead to step 5:
20 goes into 85 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 2624.0
If we subtract 80 from 85, we get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 20

Advancing to step 6:
20 can be fit into 59 2 times, resulting in a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 26242.0
If we take 40 away from 59, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
20 goes into 190 9 times with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 26242.9
Deduct 180 from 190 and we're left 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.

On to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 26242.95
Subtracting 100 from 100 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.

On to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26242.95
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.

On to step 10:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 26242.95
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 26242.95 with a remainder of 0.0.
