Let's divide 169815 by 18
We're looking to find how many times 18 goes into 169815.

Advancing to step 1:
1 divided by 18 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 18

On to step 2:
18 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 18

Advancing to step 3:
When dividing 169 by 18, we get 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 162 from 169, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 18

Moving on to step 4:
18 can be fit into 78 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Subtract 72 from 78 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 18

Advancing to step 5:
61 divided by 18 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 943.0
If we take 54 away from 61, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 18

Going ahead to step 6:
75 divided by 18 is 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 9434.0
The remainder is 3 after subtracting 72 from 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 18, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 9434.1
If we subtract 18 from 30, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 9434.16
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 18, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 9434.166
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 9434.166 with a balance of 0.0012.
