We look at the division of 97731416 by 15 
We're looking to find how many times 15 goes into 97731416.

Step 1:
The number 15 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 15

On to step 2:
97 divided by 15 is 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 90 from 97 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 15

Moving on to step 3:
If we divide 77 by 15, we get 5 and a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 65.0
If we subtract 75 from 77, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 15

On to step 4:
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: 651.0
If we take 15 away from 23, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 15

Going ahead to step 5:
If we divide 81 by 15, we get 5 and a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 6515.0
If we subtract 75 from 81, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 15

Going ahead to step 6:
The number 15 fits into 64 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 65154.0
Subtracting 60 from 64 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 15

On to step 7:
If we divide 41 by 15, we get 2 and a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 651542.0
Subtract 30 from 41 to get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 15

Moving on to step 8:
116 divided by 15 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 6515427.0
If we take 105 away from 116, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
15 goes into 110 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 6515427.7
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 6515427.73
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
15 goes into 50 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 6515427.733
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 6515427.733, with a leftover of 0.0005.
