We look at the division of 150205 by 31 
Let's see how many times 31 fits into 150205.

On to step 1:
The number 31 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
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 31

Going ahead to step 2:
31 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our 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 / 31

Advancing to step 3:
150 divided by 31 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 124 from 150 to get 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 31

Let's proceed to step 4:
When dividing 262 by 31, we get 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 48.0
Subtracting 248 from 262 leaves us with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 31

Let's proceed to step 5:
31 can be fit into 140 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 484.0
Subtract 124 from 140 to get 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 31

Let's proceed to step 6:
The number 31 fits into 165 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 4845.0
Deduct 155 from 165 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
The number 31 fits into 100 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 4845.3
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
31 can be fit into 70 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 4845.32
Deduct 62 from 70 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 9:
If we divide 80 by 31, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 4845.322
Subtracting 62 from 80 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 4845.322, with a leftover of 0.0018.
