We divide 128042 by 78
Let's see how many times 78 fits into 128042.

On to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 78

Let's proceed to step 2:
When dividing 12 by 78, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 78

Moving on to step 3:
When dividing 128 by 78, we get 1 with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 78 from 128 to get 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 78

Step 4:
78 goes into 500 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 468 from 500 to get 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 78

Moving on to step 5:
The number 78 fits into 324 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
Deduct 312 from 324 and we're left with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 78

On to step 6:
78 goes into 122 1 times with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 1641.0
If we subtract 78 from 122, we get 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 7:
If we divide 440 by 78, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1641.5
Deduct 390 from 440 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
If we divide 500 by 78, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 1641.56
Deduct 468 from 500 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
78 goes into 320 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 1641.564
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
78 goes into 80 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1641.5641
Subtract 78 from 80 to 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.

Step 11:
78 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1641.5641
Subtracting 0 from 20 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.

Advancing to step 12:
78 goes into 200 2 times with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 1641.564102
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.

Step 13:
440 divided by 78 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 1641.5641025
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.

Step 14:
When dividing 500 by 78, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1641.56410256
Deduct 468 from 500 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 1641.56410256 with a remaining 3.2e-08.
