We divide 648535 by 72
We're looking to find how many times 72 goes into 648535.

Step 1:
72 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 72

Step 2:
If we divide 64 by 72, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 72

Step 3:
If we divide 648 by 72, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 0 after subtracting 648 from 648.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 72

On to step 4:
If we divide 5 by 72, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 90.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 72

Moving on to step 5:
If we divide 53 by 72, we get 0 and a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 900.0
Deduct 0 from 53 and we're left with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 72

Let's proceed to step 6:
If we divide 535 by 72, we get 7 and a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 9007.0
If we subtract 504 from 535, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
310 divided by 72 is 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 9007.4
Subtract 288 from 310 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
72 goes into 220 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 9007.43
If we take 216 away from 220, we end up 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.

On to step 9:
The number 72 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 9007.43
Subtract 0 from 40 to 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.

Let's proceed to step 10:
The number 72 fits into 400 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 9007.4305
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 11:
72 goes into 400 5 times with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 9007.43055
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 9007.43055 and a remainder of 4e-05.
