We look at the division of 853429 by 18 
Let's see how many times 18 fits into 853429.

On to step 1:
The number 18 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 18

Step 2:
When dividing 85 by 18, we get 4 with a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 72 from 85 leaves us with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 18

Advancing to step 3:
If we divide 133 by 18, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtract 126 from 133 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 18

Let's proceed to step 4:
The number 18 fits into 74 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 474.0
Subtracting 72 from 74 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 18

Let's proceed to step 5:
22 divided by 18 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 4741.0
If we take 18 away from 22, we end up with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 18

On to step 6:
18 can be fit into 49 2 times, resulting in a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 47412.0
Subtract 36 from 49 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
The number 18 fits into 130 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 47412.7
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
The number 18 fits into 40 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 47412.72
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
18 goes into 40 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 47412.722
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 47412.722, and the remainder is 0.0004.
