903359 ÷ 18 
Let's see how many times 18 fits into 903359.

Going ahead to step 1:
18 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 18

Advancing to step 2:
If we divide 90 by 18, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 90 from 90, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 18

Moving on to step 3:
If we divide 3 by 18, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 18

Going ahead to step 4:
The number 18 fits into 33 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 501.0
Deduct 18 from 33 and we're left with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 18

Going ahead to step 5:
If we divide 155 by 18, we get 8 and a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 5018.0
Subtract 144 from 155 to get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 18

Going ahead to step 6:
When dividing 119 by 18, we get 6 with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 50186.0
Deduct 108 from 119 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
18 goes into 110 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 50186.6
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 18 fits into 20 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 50186.61
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
20 divided by 18 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 50186.611
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 50186.611 with a remaining 0.0002.
