We're dividing 339055 by 15 
Let's see how many times 15 fits into 339055.

Going ahead to step 1:
15 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 15

On to step 2:
15 goes into 33 2 times with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 30 from 33 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 15

Advancing to step 3:
If we divide 39 by 15, we get 2 and a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 9 after subtracting 30 from 39.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 15

Step 4:
90 divided by 15 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 226.0
The remainder is 0 after subtracting 90 from 90.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 15

Moving on to step 5:
If we divide 5 by 15, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 2260.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 15

Moving on to step 6:
15 goes into 55 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 22603.0
Subtract 45 from 55 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.

Advancing to step 7:
100 divided by 15 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 22603.6
Deduct 90 from 100 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.

Advancing 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: 22603.66
The remainder is 10 after subtracting 90 from 100.
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 outcome is 22603.66, with a leftover of 0.01.
