786999 ÷ 12 
Let's see how many times 12 fits into 786999.

Step 1:
12 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 12

Step 2:
When dividing 78 by 12, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 6 after subtracting 72 from 78.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 12

Step 3:
12 can be fit into 66 5 times, resulting in a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Subtract 60 from 66 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 12

On to step 4:
If we divide 69 by 12, we get 5 and a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 655.0
Subtracting 60 from 69 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 12

Advancing to step 5:
12 goes into 99 8 times with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 6558.0
Subtracting 96 from 99 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 12

Let's proceed to step 6:
The number 12 fits into 39 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 65583.0
Subtract 36 from 39 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 65583.2
Subtracting 24 from 30 leaves us with 6.
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 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 65583.25
Subtract 60 from 60 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.

Advancing to step 9:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 65583.25
Deduct 0 from 0 and we're left 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 10:
0 divided by 12 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 65583.25
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.

Our division results in 65583.25 with a remaining 0.0.
