We divide 673485 by 18
We're looking to find how many times 18 goes into 673485.

Let's proceed to step 1:
When dividing 6 by 18, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 18

Let's proceed to step 2:
If we divide 67 by 18, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 54 from 67, we get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 18

On to step 3:
The number 18 fits into 133 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtracting 126 from 133 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 18

Step 4:
18 goes into 74 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 374.0
Subtract 72 from 74 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 18

Moving on to step 5:
If we divide 28 by 18, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 3741.0
Subtract 18 from 28 to get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 18

On to step 6:
18 goes into 105 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 37415.0
Subtract 90 from 105 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
If we divide 150 by 18, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 37415.8
If we take 144 away from 150, 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.

Going ahead to step 8:
60 divided by 18 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 37415.83
If we subtract 54 from 60, we 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.

On to step 9:
When dividing 60 by 18, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 37415.833
Deduct 54 from 60 and we're left 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.

The final outcome is 37415.833, with a leftover of 0.0006.
