We divide 81869 by 12
We want to figure out the number of times 81869 can be divided by 12.

On to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 12

Step 2:
If we divide 81 by 12, we get 6 and a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 72 from 81 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 12

On to step 3:
The number 12 fits into 98 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtracting 96 from 98 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 12

Step 4:
When dividing 26 by 12, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 682.0
Subtract 24 from 26 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 12

Step 5:
If we divide 29 by 12, we get 2 and a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 6822.0
Deduct 24 from 29 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 6:
50 divided by 12 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 6822.4
If we take 48 away from 50, we end up 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.

Going ahead to step 7:
When dividing 20 by 12, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 6822.41
If we take 12 away from 20, we end up 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.

On to step 8:
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: 6822.416
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.

Going ahead to step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 6822.4166
Deduct 72 from 80 and we're left 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.

After the division, we end up with 6822.4166 and a remainder of 8e-05.
