393607 divided by 18 
We're looking to find how many times 18 goes into 393607.

Advancing to step 1:
18 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 18

On to step 2:
18 goes into 39 2 times with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 36 from 39 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 18

Moving on to step 3:
If we divide 33 by 18, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 18 from 33 and we're left with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 18

Let's proceed to step 4:
18 goes into 156 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 218.0
If we subtract 144 from 156, we get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 18

Moving on to step 5:
18 goes into 120 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 2186.0
Subtract 108 from 120 to get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 18

On to step 6:
If we divide 127 by 18, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 21867.0
Subtracting 126 from 127 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 18 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 21867.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 18, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 21867.05
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 18, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 21867.055
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 21867.055, and the remainder is 0.001.
