We're dividing 978972 by 12 
We want to figure out the number of times 978972 can be divided by 12.

Advancing to step 1:
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: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 12

On to step 2:
12 goes into 97 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 96 from 97 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 12

Advancing to step 3:
12 goes into 18 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 81.0
The remainder is 6 after subtracting 12 from 18.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 12

Let's proceed to step 4:
The number 12 fits into 69 5 times, leaving a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 815.0
The remainder is 9 after subtracting 60 from 69.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 12

Let's proceed to step 5:
If we divide 97 by 12, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 8158.0
If we take 96 away from 97, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 12

Let's proceed to step 6:
The number 12 fits into 12 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 81581.0
If we take 12 away from 12, 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.

Going ahead to step 7:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 81581.0
Deduct 0 from 0 and we're left 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.

Moving on to step 8:
0 divided by 12 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 81581.0
Deduct 0 from 0 and we're left 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 outcome is 81581.0, with a leftover of 0.0.
