We look at the division of 866337 by 18 
We want to figure out the number of times 866337 can be divided by 18.

Let's proceed to step 1:
18 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 18

Moving on to step 2:
86 divided by 18 is 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 72 away from 86, we end up with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 18

Going ahead to step 3:
The number 18 fits into 146 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we take 144 away from 146, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 18

Advancing to step 4:
The number 18 fits into 23 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 481.0
If we take 18 away from 23, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 18

Step 5:
If we divide 53 by 18, we get 2 and a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 4812.0
Deduct 36 from 53 and we're left with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 18

Moving on to step 6:
If we divide 177 by 18, we get 9 and a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 48129.0
Subtract 162 from 177 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
If we divide 150 by 18, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 48129.8
If we subtract 144 from 150, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 48129.83
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
18 can be fit into 60 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 48129.833
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 48129.833 with a remaining 0.0006.
