We're dividing 990986 by 15 
We want to divide 990986 by 15.

Going ahead to step 1:
15 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 15

On to step 2:
If we divide 99 by 15, we get 6 and a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 90 from 99 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 15

On to step 3:
15 can be fit into 90 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtract 90 from 90 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 15

Going ahead to step 4:
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: 660.0
Subtract 0 from 9 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 15

Let's proceed to step 5:
The number 15 fits into 98 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 6606.0
Subtract 90 from 98 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 15

On to step 6:
86 divided by 15 is 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 66065.0
If we take 75 away from 86, 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.

Moving on to step 7:
The number 15 fits into 110 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 66065.7
Deduct 105 from 110 and we're left 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.

Let's proceed to step 8:
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: 66065.73
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.

Going ahead to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 66065.733
Subtract 45 from 50 to get 5.
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 result is 66065.733 with a remainder of 0.0005.
