993403 divided by 18 
We're looking to find how many times 18 goes into 993403.

On to step 1:
When dividing 9 by 18, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 18

On to step 2:
99 divided by 18 is 5 with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 90 from 99 and we're left with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 18

Advancing to step 3:
The number 18 fits into 93 5 times, leaving a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtract 90 from 93 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 18

Advancing to step 4:
18 goes into 34 1 times with a remainder of 16.
The next digit of our result is 1. 
Result so far: 551.0
Subtracting 18 from 34 leaves us with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 18

Moving on to step 5:
160 divided by 18 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 5518.0
Subtracting 144 from 160 leaves us with 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 18

Moving on to step 6:
18 goes into 163 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 55189.0
Deduct 162 from 163 and we're left 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.

Let's proceed to step 7:
If we divide 10 by 18, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 55189.0
The remainder is 10 after subtracting 0 from 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:
18 goes into 100 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 55189.05
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
The number 18 fits into 100 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 55189.055
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.

In conclusion, the division gives 55189.055 with a balance of 0.001.
