123684 ÷ 9 
Our goal is to divide 123684 by 9.

Advancing to step 1:
9 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 9

Let's proceed to step 2:
9 can be fit into 12 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 9 from 12 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 9

Step 3:
9 goes into 33 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 27 from 33 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 9

Going ahead to step 4:
When dividing 66 by 9, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Subtracting 63 from 66 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 9

Advancing to step 5:
9 can be fit into 38 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 1374.0
Deduct 36 from 38 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 9

Advancing to step 6:
9 goes into 24 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 13742.0
If we subtract 18 from 24, 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.

On to step 7:
When dividing 60 by 9, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 13742.6
The remainder is 6 after subtracting 54 from 60.
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:
9 goes into 60 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 13742.66
If we take 54 away from 60, 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.

The quotient of the division is 13742.66, and the remainder is 0.006.
