We look at the division of 186015 by 72 
Let's see how many times 72 fits into 186015.

Advancing to step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 72

Let's proceed to step 2:
72 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 72

On to step 3:
If we divide 186 by 72, we get 2 and a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 144 away from 186, we end up with 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 72

Going ahead to step 4:
If we divide 420 by 72, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 360 away from 420, we end up with 60.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 72

Let's proceed to step 5:
72 can be fit into 601 8 times, resulting in a remainder of 25.
The next digit of our result is 8. 
Result so far: 258.0
If we take 576 away from 601, we end up with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 72

On to step 6:
72 can be fit into 255 3 times, resulting in a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 2583.0
If we subtract 216 from 255, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
The number 72 fits into 390 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 2583.5
If we take 360 away from 390, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 72 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 2583.54
Deduct 288 from 300 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.

Advancing to step 9:
When dividing 120 by 72, we get 1 with a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 2583.541
The remainder is 48 after subtracting 72 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
When dividing 480 by 72, we get 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 2583.5416
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 2583.54166
If we subtract 432 from 480, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 2583.54166 and a remainder of 4.8e-05.
