515034 divided by 20 
We want to figure out the number of times 515034 can be divided by 20.

Step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 20

Step 2:
The number 20 fits into 51 2 times, leaving a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 40 from 51, we get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 20

Going ahead to step 3:
When dividing 115 by 20, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we take 100 away from 115, we end up with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 20

Let's proceed to step 4:
The number 20 fits into 150 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 257.0
Subtract 140 from 150 to get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 20

On to step 5:
If we divide 103 by 20, we get 5 and a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 2575.0
Subtract 100 from 103 to get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 20

Moving on to step 6:
34 divided by 20 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 25751.0
Deduct 20 from 34 and we're left 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.

Going ahead to step 7:
140 divided by 20 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 25751.7
Subtracting 140 from 140 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.

On to step 8:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25751.7
If we take 0 away from 0, we end up 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:
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: 25751.7
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 25751.7 with a remainder of 0.0.
