Let's divide 849663 by 12
We're looking to find how many times 12 goes into 849663.

On to step 1:
12 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 12

On to step 2:
12 can be fit into 84 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 0 after subtracting 84 from 84.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 12

Let's proceed to step 3:
The number 12 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 12

Let's proceed to step 4:
The number 12 fits into 96 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 708.0
Deduct 96 from 96 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 12

Advancing to step 5:
6 divided by 12 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 7080.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 12

Step 6:
12 goes into 63 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 70805.0
Subtracting 60 from 63 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 12, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 70805.2
Deduct 24 from 30 and we're left 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 goes into 60 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 70805.25
Subtracting 60 from 60 leaves us 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.

Let's proceed to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 70805.25
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.

Moving on to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 70805.25
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.

The quotient of the division is 70805.25, and the remainder is 0.0.
