We divide 9728478 by 15
Let's see how many times 15 fits into 9728478.

On to step 1:
The number 15 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 15

On to step 2:
The number 15 fits into 97 6 times, leaving a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 90 from 97 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 15

Advancing to step 3:
If we divide 72 by 15, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
The remainder is 12 after subtracting 60 from 72.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 15

Moving on to step 4:
The number 15 fits into 128 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 648.0
If we take 120 away from 128, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 15

Going ahead to step 5:
84 divided by 15 is 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 6485.0
If we subtract 75 from 84, we get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 15

Step 6:
15 goes into 97 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 64856.0
Subtract 90 from 97 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 15

Let's proceed to step 7:
78 divided by 15 is 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 648565.0
The remainder is 3 after subtracting 75 from 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
When dividing 30 by 15, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 648565.2
Deduct 30 from 30 and we're left 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.
Record the quotient 0 as the next digit in the result. 
Result so far: 648565.2
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.

Going ahead to step 10:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 648565.2
Subtracting 0 from 0 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.

The final outcome is 648565.2, with a leftover of 0.0.
