Let's divide 636519 by 20
We want to figure out the number of times 636519 can be divided by 20.

Going ahead to step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 20

Advancing to step 2:
If we divide 63 by 20, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 60 from 63 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 20

On to step 3:
The number 20 fits into 36 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 20 from 36 to get 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 20

Moving on to step 4:
When dividing 165 by 20, we get 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 318.0
Deduct 160 from 165 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 5:
51 divided by 20 is 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 3182.0
If we take 40 away from 51, we end up with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 20

On to step 6:
The number 20 fits into 119 5 times, leaving a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 31825.0
Deduct 100 from 119 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
190 divided by 20 is 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 31825.9
If we take 180 away from 190, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

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: 31825.95
Deduct 100 from 100 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.

Let's proceed to step 9:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31825.95
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.

On to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 31825.95
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.

The final result is 31825.95 with a remainder of 0.0.
