800111 divided by 20 
We want to figure out the number of times 800111 can be divided by 20.

On to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 20

Advancing to step 2:
The number 20 fits into 80 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 80 away from 80, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 20

Step 3:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 0, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 20

On to step 4:
The number 20 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 400.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 20

Going ahead to step 5:
When dividing 11 by 20, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 4000.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 20

Let's proceed to step 6:
If we divide 111 by 20, we get 5 and a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 40005.0
Subtract 100 from 111 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 20 fits into 110 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 40005.5
Subtract 100 from 110 to 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.

Step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 40005.55
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.

In conclusion, the division gives 40005.55 with a balance of 0.0.
