Let's divide 128642 by 78
We want to figure out the number of times 128642 can be divided by 78.

Step 1:
When dividing 1 by 78, we get 0 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 / 78

Moving on to step 2:
12 divided by 78 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 78

Moving on 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.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 78

Going ahead to step 4:
78 can be fit into 506 6 times, resulting in a remainder of 38.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 38 after subtracting 468 from 506.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 78

Going ahead to step 5:
78 goes into 384 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
If we subtract 312 from 384, we get 72.
Include the next digit (2) from the dividend after 72, then repeat: 722 / 78

Let's proceed to step 6:
722 divided by 78 is 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 1649.0
Subtracting 702 from 722 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 1649.2
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
If we divide 440 by 78, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1649.25
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 1649.256
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
78 goes into 320 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 1649.2564
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
The number 78 fits into 80 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1649.25641
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
When dividing 20 by 78, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1649.25641
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
The number 78 fits into 200 2 times, leaving a remainder of 44.
The next digit of our result is 2. 
Result so far: 1649.2564102
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
440 divided by 78 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 1649.25641025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 1649.25641025, and the remainder is 5e-08.
