155690 ÷ 18 
We're looking to find how many times 18 goes into 155690.

Let's proceed to step 1:
1 divided by 18 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
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

Let's proceed to step 2:
The number 18 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 18

Let's proceed to step 3:
18 can be fit into 155 8 times, resulting in a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 144 from 155 to get 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 18

Going ahead to step 4:
If we divide 116 by 18, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 86.0
The remainder is 8 after subtracting 108 from 116.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 18

Step 5:
18 goes into 89 4 times with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 864.0
If we take 72 away from 89, we end up with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 18

Advancing to step 6:
170 divided by 18 is 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 8649.0
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
80 divided by 18 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 8649.4
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
18 goes into 80 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 8649.44
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 8649.44 with a remainder of 0.008.
