Let's divide 516558 by 20
We want to divide 516558 by 20.

On to step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 20

Let's proceed to step 2:
The number 20 fits into 51 2 times, leaving a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 40 from 51 to get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 20

Going ahead to step 3:
When dividing 116 by 20, we get 5 with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 100 from 116 and we're left with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 20

On to step 4:
165 divided by 20 is 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 258.0
Subtracting 160 from 165 leaves us with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 20

On to step 5:
55 divided by 20 is 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 2582.0
Deduct 40 from 55 and we're left with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 20

Moving on to step 6:
The number 20 fits into 158 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 25827.0
The remainder is 18 after subtracting 140 from 158.
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:
180 divided by 20 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 25827.9
If we subtract 180 from 180, 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.

Let's proceed 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: 25827.9
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.

Going ahead to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25827.9
Deduct 0 from 0 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.

In conclusion, the division gives 25827.9 with a balance of 0.0.
