Let's divide 939976 by 12
We want to figure out the number of times 939976 can be divided by 12.

Moving on to step 1:
12 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 12

Going ahead to step 2:
If we divide 93 by 12, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 84 from 93 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 12

Step 3:
12 goes into 99 8 times with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Deduct 96 from 99 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 12

Step 4:
39 divided by 12 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 783.0
Deduct 36 from 39 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 12

Let's proceed to step 5:
If we divide 37 by 12, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 7833.0
If we take 36 away from 37, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 12

Step 6:
If we divide 16 by 12, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 78331.0
Deduct 12 from 16 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 78331.3
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 78331.33
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 78331.33 and a remainder of 0.004.
