808986 ÷ 12 
We want to figure out the number of times 808986 can be divided by 12.

Step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 12

Advancing to step 2:
12 goes into 80 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 72 away from 80, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 12

Moving on to step 3:
The number 12 fits into 88 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Deduct 84 from 88 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 12

Advancing to step 4:
The number 12 fits into 49 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 674.0
Subtract 48 from 49 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 12

Step 5:
12 goes into 18 1 times with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 6741.0
Subtract 12 from 18 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 12

On to step 6:
The number 12 fits into 66 5 times, leaving a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 67415.0
The remainder is 6 after subtracting 60 from 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 67415.5
If we take 60 away from 60, 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.

Advancing to step 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 67415.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 67415.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 67415.5 and a remainder of 0.0.
