We look at the division of 135894 by 18 
We're looking to find how many times 18 goes into 135894.

Moving on to step 1:
1 divided by 18 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 18

On to step 2:
18 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 18

Let's proceed to step 3:
When dividing 135 by 18, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 9 after subtracting 126 from 135.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 18

Going ahead to step 4:
When dividing 98 by 18, we get 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 75.0
Deduct 90 from 98 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 18

On to step 5:
The number 18 fits into 89 4 times, leaving a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 754.0
Subtract 72 from 89 to get 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 18

Let's proceed to step 6:
When dividing 174 by 18, we get 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 7549.0
If we subtract 162 from 174, 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:
120 divided by 18 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 7549.6
Subtract 108 from 120 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.

Let's proceed to step 8:
When dividing 120 by 18, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 7549.66
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 result is 7549.66 with a remainder of 0.012.
