We look at the division of 805023 by 20 
We want to figure out the number of times 805023 can be divided by 20.

Step 1:
20 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 20

Step 2:
20 goes into 80 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 80 away from 80, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 20

Let's proceed to step 3:
The number 20 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 5, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 20

Step 4:
20 goes into 50 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 402.0
The remainder is 10 after subtracting 40 from 50.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 20

Moving on to step 5:
20 can be fit into 102 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 4025.0
Subtract 100 from 102 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 20

On to step 6:
20 can be fit into 23 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 40251.0
If we subtract 20 from 23, we 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.

Going ahead to step 7:
30 divided by 20 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 40251.1
Subtracting 20 from 30 leaves us 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.

Step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 40251.15
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.

On to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40251.15
If we take 0 away from 0, we end up 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 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40251.15
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 40251.15 with a remaining 0.0.
