Let's divide 978158 by 12
We're looking to find how many times 12 goes into 978158.

Moving on to step 1:
The number 12 fits into 9 0 times, leaving 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.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 12

Let's proceed to step 2:
12 goes into 97 8 times with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 96 from 97 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 12

Step 3:
The number 12 fits into 18 1 times, leaving 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.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 12

Let's proceed to step 4:
When dividing 61 by 12, we get 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 815.0
If we take 60 away from 61, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 12

Moving on to step 5:
The number 12 fits into 15 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 8151.0
Subtracting 12 from 15 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 12

Moving on to step 6:
If we divide 38 by 12, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 81513.0
Subtracting 36 from 38 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 12 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 81513.1
Subtracting 12 from 20 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 81513.16
If we subtract 72 from 80, 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 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 81513.166
If we subtract 72 from 80, 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.

In conclusion, the division gives 81513.166 with a balance of 0.0008.
