123615 ÷ 18 
We want to divide 123615 by 18.

Advancing to step 1:
When dividing 1 by 18, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 18

Step 2:
When dividing 12 by 18, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 18

Advancing to step 3:
123 divided by 18 is 6 with a remainder of 15.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 15 after subtracting 108 from 123.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 18

Let's proceed to step 4:
18 can be fit into 156 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtracting 144 from 156 leaves us with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 18

Moving on to step 5:
121 divided by 18 is 6 with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 686.0
The remainder is 13 after subtracting 108 from 121.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 18

On to step 6:
The number 18 fits into 135 7 times, leaving a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 6867.0
Deduct 126 from 135 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
When dividing 90 by 18, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6867.5
Deduct 90 from 90 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.

Let's proceed to step 8:
0 divided by 18 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6867.5
Subtracting 0 from 0 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:
18 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6867.5
If we subtract 0 from 0, we 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.

The quotient of the division is 6867.5, and the remainder is 0.0.
