398970 divided by 15 
Let's see how many times 15 fits into 398970.

Step 1:
15 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 15

On to step 2:
15 goes into 39 2 times with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 30 from 39, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 15

Going ahead to step 3:
If we divide 98 by 15, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we subtract 90 from 98, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 15

Moving on to step 4:
15 goes into 89 5 times with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 265.0
Subtracting 75 from 89 leaves us with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 15

Let's proceed to step 5:
The number 15 fits into 147 9 times, leaving a remainder of 12.
The next digit of our result is 9. 
Result so far: 2659.0
Subtract 135 from 147 to get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 15

Moving on to step 6:
If we divide 120 by 15, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 26598.0
Subtracting 120 from 120 leaves us 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.

Going ahead to step 7:
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: 26598.0
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.

Let's proceed to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 26598.0
If we subtract 0 from 0, we 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.

After the division, we end up with 26598.0 and a remainder of 0.0.
