623169 ÷ 18 
Our goal is to divide 623169 by 18.

Moving on to step 1:
6 divided by 18 is 0 with 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 (2) from the dividend, add it to 6, then carry on: 62 / 18

Advancing to step 2:
The number 18 fits into 62 3 times, leaving a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 54 from 62 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 18

Let's proceed to step 3:
18 can be fit into 83 4 times, resulting in a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtract 72 from 83 to get 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 18

Step 4:
18 goes into 111 6 times with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 346.0
If we subtract 108 from 111, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 18

Advancing to step 5:
When dividing 36 by 18, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 3462.0
If we take 36 away from 36, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 18

Going ahead to step 6:
18 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 34620.0
If we take 0 away from 9, we end up 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:
The number 18 fits into 90 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 34620.5
Subtract 90 from 90 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.

Step 8:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 34620.5
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.

Going ahead to step 9:
The number 18 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 34620.5
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 34620.5 with a balance of 0.0.
