We look at the division of 158937 by 18 
We're looking to find how many times 18 goes into 158937.

Moving on to step 1:
The number 18 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 18

Moving on to step 2:
When dividing 15 by 18, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 18

Step 3:
If we divide 158 by 18, we get 8 and a remainder of 14.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 144 from 158 to get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 18

Moving on to step 4:
18 goes into 149 8 times with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Subtract 144 from 149 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 18

Step 5:
The number 18 fits into 53 2 times, leaving a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 882.0
If we subtract 36 from 53, we get 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 18

Step 6:
The number 18 fits into 177 9 times, leaving a remainder of 15.
The next digit of our result is 9. 
Result so far: 8829.0
Subtracting 162 from 177 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
When dividing 150 by 18, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8829.8
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.

Advancing to step 8:
When dividing 60 by 18, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 8829.83
If we subtract 54 from 60, 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.

Moving on to step 9:
When dividing 60 by 18, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 8829.833
Subtracting 54 from 60 leaves us with 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 8829.833 with a remaining 0.0006.
