872013 ÷ 20 
We're looking to find how many times 20 goes into 872013.

Advancing to step 1:
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: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 20

Moving on to step 2:
20 goes into 87 4 times with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 80 from 87 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 20

Step 3:
When dividing 72 by 20, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we take 60 away from 72, we end up with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 20

Step 4:
The number 20 fits into 120 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 436.0
If we take 120 away from 120, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 20

On to step 5:
20 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 4360.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 20

On to step 6:
If we divide 13 by 20, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 43600.0
If we take 0 away from 13, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
20 can be fit into 130 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 43600.6
Deduct 120 from 130 and we're left 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.

Moving on to step 8:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 43600.65
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.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 43600.65
The remainder is 0 after subtracting 0 from 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 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43600.65
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 43600.65, and the remainder is 0.0.
