143233 ÷ 18 
We're looking to find how many times 18 goes into 143233.

Let's proceed to step 1:
If we divide 1 by 18, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 18

On to step 2:
18 can be fit into 14 0 times, resulting in a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 18

Step 3:
If we divide 143 by 18, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 126 from 143, we get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 18

Step 4:
If we divide 172 by 18, we get 9 and a remainder of 10.
The next digit of our result is 9. 
Result so far: 79.0
If we subtract 162 from 172, we get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 18

Moving on to step 5:
When dividing 103 by 18, we get 5 with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 795.0
The remainder is 13 after subtracting 90 from 103.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 18

Let's proceed to step 6:
The number 18 fits into 133 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 7957.0
If we take 126 away from 133, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
The number 18 fits into 70 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 7957.3
Subtract 54 from 70 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
160 divided by 18 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7957.38
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
When dividing 160 by 18, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 7957.388
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 7957.388, and the remainder is 0.0016.
