We're dividing 17518054 by 903 
Let's see how many times 903 fits into 17518054.

On to step 1:
When dividing 1 by 903, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 903

Moving on to step 2:
If we divide 17 by 903, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 903

Going ahead to step 3:
903 goes into 175 0 times with a remainder of 175.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 175 after subtracting 0 from 175.
Append the next digit (1) from the dividend to 175 and continue with: 1751 / 903

Let's proceed to step 4:
The number 903 fits into 1751 1 times, leaving a remainder of 848.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 848 after subtracting 903 from 1751.
Append the next digit (8) from the dividend to 848 and continue with: 8488 / 903

Going ahead to step 5:
If we divide 8488 by 903, we get 9 and a remainder of 361.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 8127 from 8488, we get 361.
Bring next digit (0) of the dividend behind the 361 and repeat the process: 3610 / 903

On to step 6:
903 goes into 3610 3 times with a remainder of 901.
The number 3 becomes the next digit in our result. 
Result so far: 193.0
Subtracting 2709 from 3610 leaves us with 901.
Take the next digit (5) from the dividend and append it to 901, then repeat: 9015 / 903

Moving on to step 7:
903 can be fit into 9015 9 times, resulting in a remainder of 888.
Put 9 as the next digit of the answer. 
Result so far: 1939.0
Subtract 8127 from 9015 to get 888.
Fetch the next digit (4) from the dividend, attach it to 888 and continue: 8884 / 903

Let's proceed to step 8:
When dividing 8884 by 903, we get 9 with a remainder of 757.
Use 9 as the next digit of our solution. 
Result so far: 19399.0
Subtracting 8127 from 8884 leaves us with 757.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7570, and continue the process.

Moving on to step 9:
7570 divided by 903 is 8 with a remainder of 346.
Put 8 as the next digit of the answer. 
Result so far: 19399.8
The remainder is 346 after subtracting 7224 from 7570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 10:
The number 903 fits into 3460 3 times, leaving a remainder of 751.
Put 3 as the next digit of the answer. 
Result so far: 19399.83
Subtracting 2709 from 3460 leaves us with 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

Step 11:
903 goes into 7510 8 times with a remainder of 286.
Record the quotient 8 as the next digit in the result. 
Result so far: 19399.838
If we subtract 7224 from 7510, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 12:
903 goes into 2860 3 times with a remainder of 151.
Write down 3 as next digit of the result. 
Result so far: 19399.8383
If we subtract 2709 from 2860, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Advancing to step 13:
903 can be fit into 1510 1 times, resulting in a remainder of 607.
The next digit of our result is 1. 
Result so far: 19399.83831
If we take 903 away from 1510, we end up with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Going ahead to step 14:
When dividing 6070 by 903, we get 6 with a remainder of 652.
Use 6 as the next digit of our solution. 
Result so far: 19399.838316
The remainder is 652 after subtracting 5418 from 6070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Let's proceed to step 15:
If we divide 6520 by 903, we get 7 and a remainder of 199.
The next digit of our result is 7. 
Result so far: 19399.8383167
If we subtract 6321 from 6520, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 16:
When dividing 1990 by 903, we get 2 with a remainder of 184.
The next digit of our result is 2. 
Result so far: 19399.83831672
If we subtract 1806 from 1990, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final result is 19399.83831672 with a remainder of 1.84e-07.
