We're dividing 868737 by 18 
We're looking to find how many times 18 goes into 868737.

Going ahead to step 1:
If we divide 8 by 18, we get 0 and 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.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 18

Advancing to step 2:
18 goes into 86 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 72 away from 86, we end up with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 18

Advancing to step 3:
148 divided by 18 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we subtract 144 from 148, we get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 18

Moving on to step 4:
If we divide 47 by 18, we get 2 and a remainder of 11.
The next digit of our result is 2. 
Result so far: 482.0
If we take 36 away from 47, we end up with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 18

On to step 5:
18 goes into 113 6 times with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 4826.0
If we subtract 108 from 113, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 18

Let's proceed to step 6:
When dividing 57 by 18, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 48263.0
Deduct 54 from 57 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
18 can be fit into 30 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 48263.1
The remainder is 12 after subtracting 18 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
18 can be fit into 120 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 48263.16
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 18 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 48263.166
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 48263.166, with a leftover of 0.0012.
