We look at the division of 117919 by 15 
Let's see how many times 15 fits into 117919.

On to step 1:
1 divided by 15 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 15

Going ahead to step 2:
11 divided by 15 is 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 15

Let's proceed to step 3:
15 can be fit into 117 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 105 from 117, we get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 15

On to step 4:
129 divided by 15 is 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we take 120 away from 129, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 15

Let's proceed to step 5:
91 divided by 15 is 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 786.0
The remainder is 1 after subtracting 90 from 91.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 15

Let's proceed to step 6:
19 divided by 15 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 7861.0
The remainder is 4 after subtracting 15 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
If we divide 40 by 15, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 7861.2
The remainder is 10 after subtracting 30 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 7861.26
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 7861.266
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 7861.266 and a remainder of 0.001.
