259571 ÷ 20 
We want to divide 259571 by 20.

Moving on to step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 20

Going ahead to step 2:
When dividing 25 by 20, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 20 from 25, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 20

Step 3:
When dividing 59 by 20, we get 2 with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 40 from 59, we get 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 20

Let's proceed to step 4:
20 can be fit into 195 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Subtract 180 from 195 to get 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 20

Going ahead to step 5:
20 goes into 157 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 1297.0
Subtract 140 from 157 to get 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 20

Moving on to step 6:
20 can be fit into 171 8 times, resulting in a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 12978.0
Subtracting 160 from 171 leaves us with 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:
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: 12978.5
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.

On to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 12978.55
Deduct 100 from 100 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.

The quotient of the division is 12978.55, and the remainder is 0.0.
