We're dividing 117917 by 78 
We want to figure out the number of times 117917 can be divided by 78.

Advancing to step 1:
78 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 78

Advancing to step 2:
78 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 78

Going ahead to step 3:
If we divide 117 by 78, we get 1 and a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 78 from 117 and we're left with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 78

Step 4:
If we divide 399 by 78, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 390 from 399 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 78

Step 5:
When dividing 91 by 78, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 151.0
If we take 78 away from 91, we end up with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 78

Going ahead to step 6:
78 can be fit into 137 1 times, resulting in a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 1511.0
If we take 78 away from 137, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
590 divided by 78 is 7 with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 1511.7
If we subtract 546 from 590, 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.

Moving on to step 8:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 1511.75
Subtract 390 from 440 to 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.

Step 9:
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: 1511.756
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
If we divide 320 by 78, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 1511.7564
The remainder is 8 after subtracting 312 from 320.
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:
If we divide 80 by 78, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 1511.75641
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: 1511.75641
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.

Going ahead to step 13:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 1511.7564102
Subtract 156 from 200 to 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.

Moving on to step 14:
If we divide 440 by 78, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 1511.75641025
If we take 390 away from 440, we end up 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.

The final result is 1511.75641025 with a remainder of 5e-08.
