We look at the division of 129886 by 72 
We want to divide 129886 by 72.

Going ahead to step 1:
72 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 72

Let's proceed to step 2:
72 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 72

On to step 3:
The number 72 fits into 129 1 times, leaving a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 72 from 129 to get 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 72

Going ahead to step 4:
The number 72 fits into 578 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 2 after subtracting 576 from 578.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 72

On to step 5:
72 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 72

Step 6:
72 can be fit into 286 3 times, resulting in a remainder of 70.
The next digit of our result is 3. 
Result so far: 1803.0
Deduct 216 from 286 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 7:
When dividing 700 by 72, we get 9 with a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 1803.9
Deduct 648 from 700 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
If we divide 520 by 72, we get 7 and a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 1803.97
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 1803.972
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
160 divided by 72 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1803.9722
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 1803.9722 and a remainder of 0.00016.
