902512 ÷ 18 
We want to figure out the number of times 902512 can be divided by 18.

Advancing to step 1:
If we divide 9 by 18, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 18

Moving on to step 2:
The number 18 fits into 90 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 90 from 90 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 18

Going ahead to step 3:
The number 18 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 50.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 18

Step 4:
If we divide 25 by 18, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 501.0
Deduct 18 from 25 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 18

Step 5:
71 divided by 18 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 5013.0
Deduct 54 from 71 and we're left with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 18

On to step 6:
The number 18 fits into 172 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 50139.0
If we subtract 162 from 172, 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 7:
18 goes into 100 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 50139.5
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.

On to step 8:
The number 18 fits into 100 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 50139.55
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 50139.55 and a remainder of 0.01.
