We're dividing 978597 by 12 
Let's see how many times 12 fits into 978597.

Step 1:
9 divided by 12 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 12

Step 2:
12 can be fit into 97 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 96 from 97 to 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 can be fit into 18 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 81.0
Subtract 12 from 18 to get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 12

Advancing to step 4:
The number 12 fits into 65 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 815.0
If we take 60 away from 65, we end up with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 12

Step 5:
59 divided by 12 is 4 with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 8154.0
If we subtract 48 from 59, we get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 12

Advancing to step 6:
117 divided by 12 is 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 81549.0
If we take 108 away from 117, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
The number 12 fits into 90 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 81549.7
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 81549.75
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 81549.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 12 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 81549.75
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.

The final result is 81549.75 with a remainder of 0.0.
