390906 ÷ 15 
We want to divide 390906 by 15.

Let's proceed to step 1:
The number 15 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 15

Let's proceed to step 2:
The number 15 fits into 39 2 times, leaving a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 30 from 39 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 15

Moving on to step 3:
When dividing 90 by 15, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 90 away from 90, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 15

Moving on to step 4:
The number 15 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 260.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 15

Step 5:
15 goes into 90 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 2606.0
Subtract 90 from 90 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 15

Step 6:
When dividing 6 by 15, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 26060.0
Subtract 0 from 6 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 15, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 26060.4
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 26060.4
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 26060.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 26060.4 with a balance of 0.0.
