128648 ÷ 78 
We want to divide 128648 by 78.

Moving on to step 1:
When dividing 1 by 78, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 78

Advancing to step 2:
The number 78 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 78

Let's proceed to step 3:
When dividing 128 by 78, we get 1 with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 78 from 128 and we're left with 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 78

Going ahead to step 4:
If we divide 506 by 78, we get 6 and a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 468 away from 506, we end up with 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 78

Step 5:
78 goes into 384 4 times with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 164.0
If we take 312 away from 384, we end up with 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 78

Moving on to step 6:
The number 78 fits into 728 9 times, leaving a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 1649.0
If we subtract 702 from 728, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
The number 78 fits into 260 3 times, leaving a remainder of 26.
The next digit of our result is 3. 
Result so far: 1649.3
Subtract 234 from 260 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
78 goes into 260 3 times with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 1649.33
If we take 234 away from 260, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 1649.33 and a remainder of 0.026.
