513650 ÷ 20 
We're looking to find how many times 20 goes into 513650.

Let's proceed to step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 20

Let's proceed to 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
Subtract 40 from 51 to get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 20

On to step 3:
20 can be fit into 113 5 times, resulting in a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 100 from 113 and we're left with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 20

Advancing to step 4:
The number 20 fits into 136 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 256.0
Deduct 120 from 136 and we're left with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 20

Let's proceed to step 5:
If we divide 165 by 20, we get 8 and a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 2568.0
If we subtract 160 from 165, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 20

Step 6:
20 can be fit into 50 2 times, resulting in a remainder of 10.
The next digit of our result is 2. 
Result so far: 25682.0
If we subtract 40 from 50, 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.

Let's proceed to step 7:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25682.5
Subtracting 100 from 100 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.

Going ahead to step 8:
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: 25682.5
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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25682.5
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.

Our division results in 25682.5 with a remaining 0.0.
