We look at the division of 185372 by 15 
Let's see how many times 15 fits into 185372.

On to step 1:
If we divide 1 by 15, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 15

Moving on to step 2:
When dividing 18 by 15, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we take 15 away from 18, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 15

Moving on to step 3:
If we divide 35 by 15, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 30 from 35 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 15

Let's proceed to step 4:
53 divided by 15 is 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Subtracting 45 from 53 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 15

On to step 5:
15 can be fit into 87 5 times, resulting in a remainder of 12.
The next digit of our result is 5. 
Result so far: 1235.0
Deduct 75 from 87 and we're left with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 15

Step 6:
The number 15 fits into 122 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 12358.0
If we take 120 away from 122, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
15 goes into 20 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 12358.1
Subtract 15 from 20 to 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.

Advancing to step 8:
15 goes into 50 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 12358.13
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.

On to step 9:
15 goes into 50 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 12358.133
The remainder is 5 after subtracting 45 from 50.
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 12358.133 with a remainder of 0.0005.
