97903 divided by 18 
We're looking to find how many times 18 goes into 97903.

Going ahead to step 1:
18 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 18

Going ahead to step 2:
When dividing 97 by 18, we get 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 90 from 97 leaves us with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 18

Moving on to step 3:
79 divided by 18 is 4 with a remainder of 7.
The next digit of our result is 4. 
Result so far: 54.0
Deduct 72 from 79 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 18

Advancing to step 4:
The number 18 fits into 70 3 times, leaving a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 543.0
Subtract 54 from 70 to get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 18

Advancing to step 5:
If we divide 163 by 18, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 5439.0
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.

Step 6:
18 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 5439.0
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.

Advancing to step 7:
100 divided by 18 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5439.05
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.

Moving on to step 8:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5439.055
Subtracting 90 from 100 leaves us 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.

The final outcome is 5439.055, with a leftover of 0.001.
