We look at the division of 239122 by 15 
Let's see how many times 15 fits into 239122.

Let's proceed to step 1:
15 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 15

On to step 2:
15 can be fit into 23 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 15 from 23 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 15

Let's proceed to step 3:
The number 15 fits into 89 5 times, leaving a remainder of 14.
The next digit of our result is 5. 
Result so far: 15.0
If we take 75 away from 89, we end up with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 15

Going ahead to step 4:
When dividing 141 by 15, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 159.0
Subtract 135 from 141 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 15

On to step 5:
The number 15 fits into 62 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1594.0
If we subtract 60 from 62, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 15

On to step 6:
When dividing 22 by 15, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 15941.0
If we subtract 15 from 22, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
15 goes into 70 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 15941.4
Deduct 60 from 70 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 15941.46
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.

Moving on to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 15941.466
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 15941.466 with a remainder of 0.001.
