We look at the division of 684159 by 12 
We want to divide 684159 by 12.

Going ahead to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 12

Let's proceed to step 2:
The number 12 fits into 68 5 times, leaving a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 8 after subtracting 60 from 68.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 12

Going ahead to step 3:
84 divided by 12 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
The remainder is 0 after subtracting 84 from 84.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 12

Moving on to step 4:
The number 12 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 570.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 12

Advancing to step 5:
When dividing 15 by 12, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 5701.0
The remainder is 3 after subtracting 12 from 15.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 12

Moving on to step 6:
When dividing 39 by 12, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 57013.0
If we take 36 away from 39, we end up 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.

On to step 7:
12 goes into 30 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 57013.2
If we subtract 24 from 30, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
12 goes into 60 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 57013.25
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.

Moving on to step 9:
12 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 57013.25
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.

On to step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 57013.25
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.

The quotient of the division is 57013.25, and the remainder is 0.0.
