515598 divided by 20 
Our goal is to divide 515598 by 20.

Advancing to step 1:
5 divided by 20 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 20

Advancing to step 2:
The number 20 fits into 51 2 times, leaving a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 40 from 51, we get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 20

Advancing to step 3:
115 divided by 20 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtract 100 from 115 to get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 20

Moving on to step 4:
20 can be fit into 155 7 times, resulting in a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 257.0
Subtracting 140 from 155 leaves us with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 20

Advancing to step 5:
When dividing 159 by 20, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 2577.0
If we take 140 away from 159, we end up with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 20

Let's proceed to step 6:
20 can be fit into 198 9 times, resulting in a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 25779.0
If we subtract 180 from 198, 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.

Let's proceed to step 7:
20 can be fit into 180 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 25779.9
Subtract 180 from 180 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.

Step 8:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25779.9
Subtract 0 from 0 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.

Advancing to step 9:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25779.9
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 25779.9 with a balance of 0.0.
