149386 divided by 18 
We want to figure out the number of times 149386 can be divided by 18.

Step 1:
18 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 18

Moving on to step 2:
The number 18 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 18

Advancing to step 3:
18 can be fit into 149 8 times, resulting in a remainder of 5.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 144 from 149 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 18

Moving on to step 4:
When dividing 53 by 18, we get 2 with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Deduct 36 from 53 and we're left with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 18

Step 5:
178 divided by 18 is 9 with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 829.0
Subtracting 162 from 178 leaves us with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 18

Moving on to step 6:
If we divide 166 by 18, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 8299.0
Subtracting 162 from 166 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
18 goes into 40 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 8299.2
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
18 can be fit into 40 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 8299.22
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 8299.22 with a remainder of 0.004.
