We look at the division of 235667 by 15 
Let's see how many times 15 fits into 235667.

Moving on to step 1:
If we divide 2 by 15, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 15

On to step 2:
15 can be fit into 23 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 15 from 23 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 15

On to step 3:
15 goes into 85 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 75 from 85 to get 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 15

Going ahead to step 4:
15 goes into 106 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 157.0
If we subtract 105 from 106, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 15

Moving on to step 5:
15 can be fit into 16 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1571.0
Subtracting 15 from 16 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 15

Moving on to step 6:
When dividing 17 by 15, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 15711.0
If we subtract 15 from 17, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 15, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 15711.1
Deduct 15 from 20 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
15 goes into 50 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 15711.13
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 15711.133
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 15711.133 with a remainder of 0.0005.
