We're dividing 872051 by 20 
We're looking to find how many times 20 goes into 872051.

Let's proceed to step 1:
The number 20 fits into 8 0 times, leaving 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.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 20

Moving on to step 2:
If we divide 87 by 20, we get 4 and a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 80 from 87 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 20

Advancing to step 3:
20 can be fit into 72 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtract 60 from 72 to get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 20

Going ahead to step 4:
20 can be fit into 120 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 436.0
If we subtract 120 from 120, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 20

On to step 5:
5 divided by 20 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 4360.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 20

Going ahead to step 6:
20 goes into 51 2 times with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 43602.0
Deduct 40 from 51 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 20 fits into 110 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 43602.5
If we subtract 100 from 110, we 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:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 43602.55
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.

In conclusion, the division gives 43602.55 with a balance of 0.0.
