849648 ÷ 18 
We want to figure out the number of times 849648 can be divided by 18.

On to step 1:
If we divide 8 by 18, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 18

Going ahead to step 2:
The number 18 fits into 84 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 72 from 84 leaves us with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 18

Step 3:
129 divided by 18 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 47.0
If we take 126 away from 129, we end up with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 18

Step 4:
When dividing 36 by 18, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 472.0
If we subtract 36 from 36, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 18

Moving on to step 5:
18 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 4720.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 18

Let's proceed to step 6:
If we divide 48 by 18, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 47202.0
If we subtract 36 from 48, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
When dividing 120 by 18, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 47202.6
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
18 goes into 120 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 47202.66
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 47202.66 with a remainder of 0.012.
