138396 divided by 18 
We want to divide 138396 by 18.

Moving on to step 1:
18 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 18

Moving on to step 2:
The number 18 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 18

Moving on to step 3:
The number 18 fits into 138 7 times, leaving a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 126 away from 138, we end up with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 18

Let's proceed to step 4:
If we divide 123 by 18, we get 6 and a remainder of 15.
The next digit of our result is 6. 
Result so far: 76.0
The remainder is 15 after subtracting 108 from 123.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 18

Step 5:
The number 18 fits into 159 8 times, leaving a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 768.0
Deduct 144 from 159 and we're left with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 18

Moving on to step 6:
18 can be fit into 156 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 7688.0
If we subtract 144 from 156, 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.

Advancing to step 7:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 7688.6
The remainder is 12 after subtracting 108 from 120.
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:
120 divided by 18 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 7688.66
If we subtract 108 from 120, 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.

Our division results in 7688.66 with a remaining 0.012.
