We look at the division of 150855 by 45 
We want to divide 150855 by 45.

Advancing to step 1:
The number 45 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 45

Step 2:
If we divide 15 by 45, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 45

On to step 3:
If we divide 150 by 45, we get 3 and a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 135 away from 150, we end up with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 45

On to step 4:
45 can be fit into 158 3 times, resulting in a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 135 from 158 and we're left with 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 45

Let's proceed to step 5:
When dividing 235 by 45, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 335.0
Subtracting 225 from 235 leaves us with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 45

On to step 6:
45 can be fit into 105 2 times, resulting in a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 3352.0
If we subtract 90 from 105, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
45 goes into 150 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 3352.3
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3352.33
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 3352.33 with a remainder of 0.015.
