128988 ÷ 78 
Our goal is to divide 128988 by 78.

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.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 78

Moving on to step 2:
78 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 78

Going ahead to step 3:
When dividing 128 by 78, we get 1 with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 50 after subtracting 78 from 128.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 78

On to step 4:
When dividing 509 by 78, we get 6 with a remainder of 41.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 468 from 509 leaves us with 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 78

Step 5:
78 goes into 418 5 times with a remainder of 28.
The next digit of our result is 5. 
Result so far: 165.0
Subtract 390 from 418 to get 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 78

Let's proceed to step 6:
78 can be fit into 288 3 times, resulting in a remainder of 54.
The next digit of our result is 3. 
Result so far: 1653.0
Deduct 234 from 288 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
When dividing 540 by 78, we get 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 1653.6
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 8:
78 goes into 720 9 times with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 1653.69
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
78 can be fit into 180 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 1653.692
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
When dividing 240 by 78, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 1653.6923
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
If we divide 60 by 78, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1653.6923
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
If we divide 600 by 78, we get 7 and a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 1653.692307
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
540 divided by 78 is 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 1653.6923076
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
78 goes into 720 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 1653.69230769
Subtracting 702 from 720 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 1653.69230769, and the remainder is 1.8e-08.
