We look at the division of 13266639 by 72 
We're looking to find how many times 72 goes into 13266639.

Step 1:
1 divided by 72 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 72

Let's proceed to step 2:
72 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 72

Let's proceed to step 3:
72 can be fit into 132 1 times, resulting in a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 72 from 132 leaves us with 60.
Fetch the next digit (6) from the dividend, attach it to 60 and continue: 606 / 72

On to step 4:
The number 72 fits into 606 8 times, leaving a remainder of 30.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 576 from 606 to get 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 72

Advancing to step 5:
72 goes into 306 4 times with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 184.0
If we take 288 away from 306, we end up with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 72

Let's proceed to step 6:
When dividing 186 by 72, we get 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 1842.0
Subtract 144 from 186 to get 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 72

Let's proceed to step 7:
72 can be fit into 423 5 times, resulting in a remainder of 63.
The number 5 becomes the next digit in our result. 
Result so far: 18425.0
Deduct 360 from 423 and we're left with 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 72

Advancing to step 8:
72 can be fit into 639 8 times, resulting in a remainder of 63.
Record the quotient 8 as the next digit in the result. 
Result so far: 184258.0
Subtracting 576 from 639 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 9:
72 goes into 630 8 times with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 184258.8
Deduct 576 from 630 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
72 goes into 540 7 times with a remainder of 36.
The next digit of our result is 7. 
Result so far: 184258.87
Deduct 504 from 540 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
The number 72 fits into 360 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 184258.875
Deduct 360 from 360 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
72 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 184258.875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
0 divided by 72 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 184258.875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 184258.875 with a remainder of 0.0.
