128748 ÷ 18 
We want to figure out the number of times 128748 can be divided by 18.

On to step 1:
18 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 18

Let's proceed to step 2:
When dividing 12 by 18, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 18

Going ahead to step 3:
The number 18 fits into 128 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 2 after subtracting 126 from 128.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 18

Step 4:
18 goes into 27 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 71.0
The remainder is 9 after subtracting 18 from 27.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 18

Step 5:
If we divide 94 by 18, we get 5 and a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 715.0
Subtract 90 from 94 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 18

Step 6:
48 divided by 18 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 7152.0
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:
120 divided by 18 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 7152.6
Subtracting 108 from 120 leaves us with 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:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 7152.66
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 7152.66 and a remainder of 0.012.
