81951067 divided by 12 
Our goal is to divide 81951067 by 12.

Moving on to step 1:
12 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 12

Moving on to step 2:
12 can be fit into 81 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 72 away from 81, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 12

On to step 3:
99 divided by 12 is 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Deduct 96 from 99 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 12

Going ahead to step 4:
When dividing 35 by 12, we get 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 682.0
Deduct 24 from 35 and we're left with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 12

Going ahead to step 5:
12 goes into 111 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 6829.0
Subtracting 108 from 111 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 12

Let's proceed to step 6:
If we divide 30 by 12, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 68292.0
The remainder is 6 after subtracting 24 from 30.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 12

Moving on to step 7:
If we divide 66 by 12, we get 5 and a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 682925.0
If we take 60 away from 66, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 12

Let's proceed to step 8:
12 goes into 67 5 times with a remainder of 7.
The next digit of our result is 5. 
Result so far: 6829255.0
The remainder is 7 after subtracting 60 from 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
If we divide 70 by 12, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 6829255.5
Subtract 60 from 70 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 6829255.58
If we subtract 96 from 100, we 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.

Let's proceed to step 11:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 6829255.583
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.

Going ahead to step 12:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 6829255.5833
The remainder is 4 after subtracting 36 from 40.
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 6829255.5833 and a remainder of 4e-05.
