820088 divided by 20 
Let's see how many times 20 fits into 820088.

Going ahead to step 1:
20 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 20

On to step 2:
82 divided by 20 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 80 away from 82, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 20

Let's proceed to step 3:
20 can be fit into 20 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 20 from 20 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 20

Step 4:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 410.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 20

Going ahead to step 5:
If we divide 8 by 20, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 4100.0
If we take 0 away from 8, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 20

Going ahead to step 6:
20 can be fit into 88 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 41004.0
Deduct 80 from 88 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 20, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 41004.4
Subtract 80 from 80 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.

Step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 41004.4
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.

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: 41004.4
Deduct 0 from 0 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.

Our division results in 41004.4 with a remaining 0.0.
