We're dividing 140434 by 18 
We want to divide 140434 by 18.

Going ahead to step 1:
The number 18 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 18

Going ahead to step 2:
18 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 18

Step 3:
18 can be fit into 140 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 126 from 140, we get 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 18

Moving on to step 4:
When dividing 144 by 18, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 78.0
The remainder is 0 after subtracting 144 from 144.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 18

Let's proceed to step 5:
3 divided by 18 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 780.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 18

Step 6:
The number 18 fits into 34 1 times, leaving a remainder of 16.
The next digit of our result is 1. 
Result so far: 7801.0
Subtract 18 from 34 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.

Step 7:
If we divide 160 by 18, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 7801.8
If we subtract 144 from 160, we 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.

Let's proceed to step 8:
When dividing 160 by 18, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 7801.88
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.

The quotient of the division is 7801.88, and the remainder is 0.016.
