Let's divide 139752 by 78
Let's see how many times 78 fits into 139752.

Advancing 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.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 78

Going ahead to step 2:
78 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 78

Step 3:
When dividing 139 by 78, we get 1 with a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 61 after subtracting 78 from 139.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 78

Going ahead to step 4:
78 goes into 617 7 times with a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 546 from 617 leaves us with 71.
Append the next digit (5) from the dividend to 71 and continue with: 715 / 78

Step 5:
78 can be fit into 715 9 times, resulting in a remainder of 13.
The next digit of our result is 9. 
Result so far: 179.0
If we subtract 702 from 715, we get 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 78

Step 6:
132 divided by 78 is 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 1791.0
If we take 78 away from 132, we end up 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:
540 divided by 78 is 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 1791.6
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.

Moving on to step 8:
When dividing 720 by 78, we get 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 1791.69
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.

Advancing to step 9:
180 divided by 78 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 1791.692
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
If we divide 240 by 78, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 1791.6923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
If we divide 60 by 78, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1791.6923
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.

Let's proceed 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: 1791.692307
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 13:
78 goes into 540 6 times with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 1791.6923076
If we subtract 468 from 540, we get 72.
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:
When dividing 720 by 78, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 1791.69230769
If we take 702 away from 720, we end up 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 final outcome is 1791.69230769, with a leftover of 1.8e-08.
