We're dividing 117960 by 78 
Let's see how many times 78 fits into 117960.

Step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 78

Let's proceed to step 2:
78 goes into 11 0 times with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 78

Advancing to step 3:
117 divided by 78 is 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 78 from 117 leaves us with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 78

On to step 4:
78 can be fit into 399 5 times, resulting in a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 9 after subtracting 390 from 399.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 78

On to step 5:
If we divide 96 by 78, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 151.0
If we take 78 away from 96, we end up with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 78

Going ahead to step 6:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 1512.0
Deduct 156 from 180 and we're left 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.

Going ahead to step 7:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 1512.3
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
78 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 1512.3
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
600 divided by 78 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 1512.307
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.

Step 10:
When dividing 540 by 78, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 1512.3076
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 11:
If we divide 720 by 78, we get 9 and a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 1512.30769
Deduct 702 from 720 and we're left 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.

Step 12:
180 divided by 78 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 1512.307692
Deduct 156 from 180 and we're left 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 13:
78 can be fit into 240 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 1512.3076923
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
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: 1512.3076923
Deduct 0 from 60 and we're left 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.

Our division results in 1512.3076923 with a remaining 6e-08.
