We look at the division of 903597 by 18 
We want to figure out the number of times 903597 can be divided by 18.

Moving on to step 1:
When dividing 9 by 18, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 18

Step 2:
If we divide 90 by 18, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 90 from 90 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 18

On to step 3:
3 divided by 18 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 18

Step 4:
If we divide 35 by 18, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 501.0
Deduct 18 from 35 and we're left with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 18

Let's proceed to step 5:
The number 18 fits into 179 9 times, leaving a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 5019.0
If we take 162 away from 179, we end up with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 18

Going ahead to step 6:
When dividing 177 by 18, we get 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 50199.0
Subtract 162 from 177 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:
150 divided by 18 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 50199.8
The remainder is 6 after subtracting 144 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
If we divide 60 by 18, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 50199.83
Subtracting 54 from 60 leaves us 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.

On to step 9:
18 can be fit into 60 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 50199.833
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 50199.833 with a balance of 0.0006.
