138225 divided by 18 
Our goal is to divide 138225 by 18.

Going ahead to step 1:
When dividing 1 by 18, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 18

Moving on to step 2:
When dividing 13 by 18, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 18

Moving on to step 3:
18 can be fit into 138 7 times, resulting in a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 126 from 138 to get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 18

On to step 4:
18 goes into 122 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 76.0
If we subtract 108 from 122, we get 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 18

Let's proceed to step 5:
18 can be fit into 142 7 times, resulting in a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 767.0
If we take 126 away from 142, we end up with 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 18

Step 6:
The number 18 fits into 165 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 7679.0
The remainder is 3 after subtracting 162 from 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 18 fits into 30 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 7679.1
Subtract 18 from 30 to 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.

Step 8:
When dividing 120 by 18, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 7679.16
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.

On to step 9:
18 can be fit into 120 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 7679.166
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.

The final outcome is 7679.166, with a leftover of 0.0012.
