Let's divide 129316 by 72
We're looking to find how many times 72 goes into 129316.

Step 1:
72 goes into 1 0 times with 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.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 72

Moving on to step 2:
12 divided by 72 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 72

Let's proceed to step 3:
The number 72 fits into 129 1 times, leaving a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 72 from 129 to get 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 72

Moving on to step 4:
72 goes into 573 7 times with a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 504 from 573 to get 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 72

Step 5:
72 goes into 691 9 times with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 179.0
If we subtract 648 from 691, we get 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 72

Going ahead to step 6:
If we divide 436 by 72, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 1796.0
Deduct 432 from 436 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
The number 72 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1796.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
If we divide 400 by 72, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 1796.05
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
72 can be fit into 400 5 times, resulting in a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 1796.055
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 1796.055 and a remainder of 0.004.
