142008 ÷ 18 
We want to divide 142008 by 18.

On to step 1:
When dividing 1 by 18, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 18

On to step 2:
When dividing 14 by 18, we get 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 18

Going ahead to step 3:
142 divided by 18 is 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 126 from 142, we get 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 18

Moving on to step 4:
When dividing 160 by 18, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtract 144 from 160 to get 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 18

Step 5:
160 divided by 18 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 788.0
Subtract 144 from 160 to get 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 18

Step 6:
18 goes into 168 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 7889.0
Subtract 162 from 168 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.

Advancing to step 7:
60 divided by 18 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 7889.3
If we take 54 away from 60, we end up 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.

Step 8:
If we divide 60 by 18, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 7889.33
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.

The final result is 7889.33 with a remainder of 0.006.
