We look at the division of 978009 by 12 
Our goal is to divide 978009 by 12.

Let's proceed to step 1:
The number 12 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.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 12

Going ahead to step 2:
If we divide 97 by 12, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 96 from 97, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 12

Let's proceed to step 3:
12 goes into 18 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtracting 12 from 18 leaves us with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 12

On to step 4:
60 divided by 12 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 815.0
Deduct 60 from 60 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 12

Advancing to step 5:
12 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8150.0
Subtract 0 from 0 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 12

Moving on to step 6:
12 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 81500.0
Subtract 0 from 9 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
If we divide 90 by 12, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 81500.7
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 12 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 81500.75
Subtracting 60 from 60 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 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 81500.75
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.

On to step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 81500.75
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.

After the division, we end up with 81500.75 and a remainder of 0.0.
