Let's divide 612280 by 18
We want to figure out the number of times 612280 can be divided by 18.

Step 1:
If we divide 6 by 18, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 18

Moving on to step 2:
18 goes into 61 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 54 away from 61, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 18

On to step 3:
18 goes into 72 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Deduct 72 from 72 and we're left with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 18

Moving on to step 4:
2 divided by 18 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 340.0
If we subtract 0 from 2, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 18

Advancing to step 5:
18 can be fit into 28 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 3401.0
Deduct 18 from 28 and we're left with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 18

On to step 6:
When dividing 100 by 18, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 34015.0
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.

Going ahead to step 7:
18 goes into 100 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 34015.5
Deduct 90 from 100 and we're left 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.

Advancing to step 8:
100 divided by 18 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 34015.55
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.

The final result is 34015.55 with a remainder of 0.01.
