We're dividing 988392 by 12 
Let's see how many times 12 fits into 988392.

Step 1:
9 divided by 12 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 12

Going ahead to step 2:
98 divided by 12 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 8.0
If we take 96 away from 98, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 12

On to step 3:
28 divided by 12 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 82.0
The remainder is 4 after subtracting 24 from 28.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 12

Advancing to step 4:
12 can be fit into 43 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 823.0
If we take 36 away from 43, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 12

Moving on to step 5:
When dividing 79 by 12, we get 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 8236.0
If we take 72 away from 79, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 12

Moving on to step 6:
The number 12 fits into 72 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 82366.0
Subtracting 72 from 72 leaves us 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.

Step 7:
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: 82366.0
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.

Going ahead to step 8:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 82366.0
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 82366.0, with a leftover of 0.0.
