517603 divided by 20 
Let's see how many times 20 fits into 517603.

Let's proceed to step 1:
20 can be fit into 5 0 times, resulting in 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

Advancing to step 2:
20 can be fit into 51 2 times, resulting in a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 40 away from 51, we end up with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 20

Let's proceed to step 3:
If we divide 117 by 20, we get 5 and a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 100 away from 117, we end up with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 20

Let's proceed to step 4:
When dividing 176 by 20, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 258.0
Deduct 160 from 176 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 20

On to step 5:
The number 20 fits into 160 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 2588.0
The remainder is 0 after subtracting 160 from 160.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 20

On to step 6:
The number 20 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 25880.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 25880.1
If we subtract 20 from 30, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 25880.15
Subtract 100 from 100 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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 25880.15
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 10:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 25880.15
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.

Our division results in 25880.15 with a remaining 0.0.
