259218 divided by 20 
We want to figure out the number of times 259218 can be divided by 20.

Advancing to step 1:
20 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 20

Let's proceed 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
The remainder is 5 after subtracting 20 from 25.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 20

Going ahead to step 3:
When dividing 59 by 20, we get 2 with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 40 from 59 and we're left with 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 20

Step 4:
20 goes into 192 9 times with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Subtract 180 from 192 to get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 20

On to step 5:
121 divided by 20 is 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 1296.0
If we take 120 away from 121, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 20

Step 6:
When dividing 18 by 20, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 12960.0
If we subtract 0 from 18, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
When dividing 180 by 20, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 12960.9
The remainder is 0 after subtracting 180 from 180.
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:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12960.9
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.

Moving on to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12960.9
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.

In conclusion, the division gives 12960.9 with a balance of 0.0.
