We're dividing 87220 by 18 
Our goal is to divide 87220 by 18.

On to step 1:
18 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 18

On to step 2:
The number 18 fits into 87 4 times, leaving a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 72 from 87 to get 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 18

Step 3:
152 divided by 18 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtracting 144 from 152 leaves us with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 18

Moving on to step 4:
If we divide 82 by 18, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 484.0
If we take 72 away from 82, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 18

Advancing to step 5:
100 divided by 18 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 4845.0
If we subtract 90 from 100, 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.

On to step 6:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 4845.5
Subtract 90 from 100 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 7:
100 divided by 18 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 4845.55
Deduct 90 from 100 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.

Our division results in 4845.55 with a remaining 0.01.
