We look at the division of 259994 by 20 
We're looking to find how many times 20 goes into 259994.

Moving on to step 1:
20 goes into 2 0 times with 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

On to step 2:
If we divide 25 by 20, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 20 from 25 to get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 20

Moving on to step 3:
59 divided by 20 is 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 40 from 59 to get 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 20

On to step 4:
If we divide 199 by 20, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we subtract 180 from 199, we get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 20

Let's proceed to step 5:
When dividing 199 by 20, we get 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 1299.0
If we subtract 180 from 199, we get 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 20

On to step 6:
20 goes into 194 9 times with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 12999.0
If we take 180 away from 194, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
If we divide 140 by 20, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 12999.7
If we subtract 140 from 140, 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.

On to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12999.7
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.

Going ahead to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12999.7
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.

The final result is 12999.7 with a remainder of 0.0.
