We divide 127839 by 78
We want to figure out the number of times 127839 can be divided by 78.

On to step 1:
78 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 78

Going ahead to step 2:
If we divide 12 by 78, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 78

Step 3:
When dividing 127 by 78, we get 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 1.0
If we take 78 away from 127, we end up with 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 78

Advancing to step 4:
78 can be fit into 498 6 times, resulting in a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 468 away from 498, we end up with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 78

Let's proceed to step 5:
When dividing 303 by 78, we get 3 with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 163.0
If we subtract 234 from 303, we get 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 78

Going ahead to step 6:
If we divide 699 by 78, we get 8 and a remainder of 75.
Write down 8 as next digit of the result. 
Result so far: 1638.0
If we subtract 624 from 699, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 7:
When dividing 750 by 78, we get 9 with a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 1638.9
Subtracting 702 from 750 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
480 divided by 78 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 1638.96
If we take 468 away from 480, we end up 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.

Let's proceed to step 9:
When dividing 120 by 78, we get 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 1638.961
If we take 78 away from 120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1638.9615
Subtracting 390 from 420 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
If we divide 300 by 78, we get 3 and a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 1638.96153
The remainder is 66 after subtracting 234 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 12:
78 goes into 660 8 times with a remainder of 36.
The next digit of our result is 8. 
Result so far: 1638.961538
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
78 can be fit into 360 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 1638.9615384
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
When dividing 480 by 78, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 1638.96153846
Subtracting 468 from 480 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.

In conclusion, the division gives 1638.96153846 with a balance of 1.2e-08.
