873118 ÷ 20 
We want to figure out the number of times 873118 can be divided by 20.

On to step 1:
8 divided by 20 is 0 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 (7) from the dividend, add it to 8, then carry on: 87 / 20

Advancing to step 2:
If we divide 87 by 20, we get 4 and a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 7 after subtracting 80 from 87.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 20

Advancing to step 3:
If we divide 73 by 20, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Deduct 60 from 73 and we're left with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 20

Step 4:
When dividing 131 by 20, we get 6 with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 436.0
If we take 120 away from 131, we end up with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 20

On to step 5:
When dividing 111 by 20, we get 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 4365.0
If we take 100 away from 111, we end up with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 20

Advancing to step 6:
20 goes into 118 5 times with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 43655.0
If we subtract 100 from 118, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
When dividing 180 by 20, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 43655.9
Deduct 180 from 180 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.

Advancing to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 43655.9
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.

On to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43655.9
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.

In conclusion, the division gives 43655.9 with a balance of 0.0.
