We look at the division of 975966 by 12 
Let's see how many times 12 fits into 975966.

Advancing to step 1:
When dividing 9 by 12, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 12

Let's proceed to step 2:
97 divided by 12 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 96 away from 97, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 12

Moving on to step 3:
If we divide 15 by 12, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 81.0
Deduct 12 from 15 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 12

Going ahead to step 4:
If we divide 39 by 12, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 813.0
Deduct 36 from 39 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 12

Step 5:
36 divided by 12 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 8133.0
If we subtract 36 from 36, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 12

Advancing to step 6:
If we divide 6 by 12, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 81330.0
Deduct 0 from 6 and we're left 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 7:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 81330.5
Subtract 60 from 60 to 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.

Moving on to step 8:
0 divided by 12 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 81330.5
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.

Advancing to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 81330.5
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 outcome is 81330.5, with a leftover of 0.0.
