Let's divide 646782 by 12
Our goal is to divide 646782 by 12.

On to step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 12

Let's proceed to step 2:
When dividing 64 by 12, we get 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 60 from 64 to get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 12

Step 3:
46 divided by 12 is 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Subtracting 36 from 46 leaves us with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 12

Going ahead to step 4:
The number 12 fits into 107 8 times, leaving a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 538.0
Deduct 96 from 107 and we're left with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 12

Advancing to step 5:
12 can be fit into 118 9 times, resulting in a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 5389.0
The remainder is 10 after subtracting 108 from 118.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 12

On to step 6:
12 goes into 102 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 53898.0
If we take 96 away from 102, we end up 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.

Advancing 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: 53898.5
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.

Step 8:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 53898.5
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.

On to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 53898.5
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.

The quotient of the division is 53898.5, and the remainder is 0.0.
