Let's divide 415729 by 72
We want to figure out the number of times 415729 can be divided by 72.

On to step 1:
4 divided by 72 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 72

Step 2:
41 divided by 72 is 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Fetch the next digit (5) from the dividend, attach it to 41 and continue: 415 / 72

Moving on to step 3:
72 goes into 415 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 55 after subtracting 360 from 415.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 72

Advancing to step 4:
557 divided by 72 is 7 with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
If we subtract 504 from 557, we get 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 72

On to step 5:
When dividing 532 by 72, we get 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 577.0
Subtract 504 from 532 to get 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 72

Advancing to step 6:
72 goes into 289 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 5774.0
Subtracting 288 from 289 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 72, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 5774.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
72 can be fit into 100 1 times, resulting in a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 5774.01
Deduct 72 from 100 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
If we divide 280 by 72, we get 3 and a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 5774.013
The remainder is 64 after subtracting 216 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 5774.0138
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
When dividing 640 by 72, we get 8 with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 5774.01388
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 5774.01388, with a leftover of 6.4e-05.
