We look at the division of 20356005 by 817 
We want to figure out the number of times 20356005 can be divided by 817.

Going ahead to step 1:
If we divide 2 by 817, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 817

Moving on to step 2:
If we divide 20 by 817, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 817

Advancing to step 3:
817 goes into 203 0 times with a remainder of 203.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 203, we get 203.
Fetch the next digit (5) from the dividend, attach it to 203 and continue: 2035 / 817

Going ahead to step 4:
817 can be fit into 2035 2 times, resulting in a remainder of 401.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1634 away from 2035, we end up with 401.
Grab the next digit (6) from the dividend, add it to 401, then carry on: 4016 / 817

Let's proceed to step 5:
If we divide 4016 by 817, we get 4 and a remainder of 748.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 3268 away from 4016, we end up with 748.
Include the next digit (0) from the dividend after 748, then repeat: 7480 / 817

Moving on to step 6:
When dividing 7480 by 817, we get 9 with a remainder of 127.
Put 9 as the next digit of the answer. 
Result so far: 249.0
Deduct 7353 from 7480 and we're left with 127.
Fetch the next digit (0) from the dividend, attach it to 127 and continue: 1270 / 817

Step 7:
The number 817 fits into 1270 1 times, leaving a remainder of 453.
Record the quotient 1 as the next digit in the result. 
Result so far: 2491.0
If we take 817 away from 1270, we end up with 453.
Append the next digit (5) from the dividend to 453 and continue with: 4535 / 817

Advancing to step 8:
When dividing 4535 by 817, we get 5 with a remainder of 450.
The next digit of our result is 5. 
Result so far: 24915.0
The remainder is 450 after subtracting 4085 from 4535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 9:
4500 divided by 817 is 5 with a remainder of 415.
Record the quotient 5 as the next digit in the result. 
Result so far: 24915.5
If we take 4085 away from 4500, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 10:
4150 divided by 817 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 24915.55
If we take 4085 away from 4150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 24915.55, and the remainder is 0.065.
