We're dividing 669085 by 18 
Let's see how many times 18 fits into 669085.

Going ahead to step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 18

Step 2:
18 can be fit into 66 3 times, resulting in a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 12 after subtracting 54 from 66.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 18

Moving on to step 3:
The number 18 fits into 129 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtracting 126 from 129 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 18

On to step 4:
30 divided by 18 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 371.0
Deduct 18 from 30 and we're left with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 18

Step 5:
The number 18 fits into 128 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 3717.0
Subtract 126 from 128 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 18

Let's proceed to step 6:
18 can be fit into 25 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 37171.0
Deduct 18 from 25 and we're left 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.

Step 7:
18 can be fit into 70 3 times, resulting in a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 37171.3
If we take 54 away from 70, we end up 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.

Going ahead to step 8:
18 can be fit into 160 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 37171.38
The remainder is 16 after subtracting 144 from 160.
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.
The number 8 becomes the next digit in our result. 
Result so far: 37171.388
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.

After the division, we end up with 37171.388 and a remainder of 0.0016.
