Let's divide 871486 by 18
We want to figure out the number of times 871486 can be divided by 18.

Advancing to step 1:
18 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 18

Going ahead to step 2:
When dividing 87 by 18, we get 4 with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 72 from 87, we get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 18

Let's proceed to step 3:
18 goes into 151 8 times with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
The remainder is 7 after subtracting 144 from 151.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 18

Let's proceed to step 4:
18 goes into 74 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 484.0
Deduct 72 from 74 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 18

On to step 5:
18 can be fit into 28 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 4841.0
If we subtract 18 from 28, we get 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 18

Step 6:
If we divide 106 by 18, we get 5 and a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 48415.0
Subtracting 90 from 106 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
When dividing 160 by 18, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 48415.8
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
160 divided by 18 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 48415.88
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 48415.88 with a remaining 0.016.
