865512 divided by 18 
We're looking to find how many times 18 goes into 865512.

Step 1:
When dividing 8 by 18, we get 0 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.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 18

Advancing to step 2:
86 divided by 18 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 72 away from 86, we end up with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 18

Step 3:
18 can be fit into 145 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we take 144 away from 145, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 18

On to step 4:
If we divide 15 by 18, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 480.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 18

Advancing to step 5:
If we divide 151 by 18, we get 8 and a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 4808.0
If we subtract 144 from 151, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 18

Going ahead to step 6:
72 divided by 18 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 48084.0
Deduct 72 from 72 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.

Moving on to step 7:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48084.0
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 8:
When dividing 0 by 18, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 48084.0
Subtract 0 from 0 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.

Our division results in 48084.0 with a remaining 0.0.
