81930 ÷ 12 
We're looking to find how many times 12 goes into 81930.

Let's proceed to step 1:
8 divided by 12 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 12

Moving on to step 2:
12 can be fit into 81 6 times, resulting in a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 72 from 81 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 12

On to step 3:
99 divided by 12 is 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 68.0
Subtracting 96 from 99 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 12

Moving on to step 4:
When dividing 33 by 12, we get 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 682.0
Subtracting 24 from 33 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 12

Moving on to step 5:
If we divide 90 by 12, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 6827.0
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 6:
When dividing 60 by 12, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6827.5
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6827.5
The remainder is 0 after subtracting 0 from 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:
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: 6827.5
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 6827.5, with a leftover of 0.0.
