996578 ÷ 15 
Our goal is to divide 996578 by 15.

Going ahead to step 1:
15 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 15

On to step 2:
If we divide 99 by 15, we get 6 and a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 9 after subtracting 90 from 99.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 15

Step 3:
15 can be fit into 96 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Deduct 90 from 96 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 15

Going ahead to step 4:
15 goes into 65 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 664.0
If we take 60 away from 65, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 15

Let's proceed to step 5:
15 goes into 57 3 times with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 6643.0
If we subtract 45 from 57, we get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 15

Step 6:
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: 66438.0
If we subtract 120 from 128, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
If we divide 80 by 15, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 66438.5
Deduct 75 from 80 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.

On to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 66438.53
Deduct 45 from 50 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.

On to step 9:
50 divided by 15 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 66438.533
Subtracting 45 from 50 leaves us 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.

The quotient of the division is 66438.533, and the remainder is 0.0005.
