We look at the division of 155401 by 18 
We're looking to find how many times 18 goes into 155401.

Going ahead to step 1:
When dividing 1 by 18, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 18

On to step 2:
If we divide 15 by 18, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 18

On to step 3:
If we divide 155 by 18, we get 8 and a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 11 after subtracting 144 from 155.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 18

Advancing to step 4:
18 can be fit into 114 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Deduct 108 from 114 and we're left with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 18

Going ahead to step 5:
60 divided by 18 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 863.0
If we subtract 54 from 60, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 18

Step 6:
If we divide 61 by 18, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 8633.0
The remainder is 7 after subtracting 54 from 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
18 goes into 70 3 times with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 8633.3
Subtract 54 from 70 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
18 goes into 160 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 8633.38
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
18 goes into 160 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 8633.388
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 8633.388 with a balance of 0.0016.
