539721 ÷ 72 
We want to figure out the number of times 539721 can be divided by 72.

Going ahead to step 1:
72 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 72

Step 2:
When dividing 53 by 72, we get 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 72

On to step 3:
72 goes into 539 7 times with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 35 after subtracting 504 from 539.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 72

Moving on to step 4:
The number 72 fits into 357 4 times, leaving a remainder of 69.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtracting 288 from 357 leaves us with 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 72

On to step 5:
692 divided by 72 is 9 with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 749.0
If we take 648 away from 692, we end up with 44.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 72

Moving on to step 6:
72 can be fit into 441 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 7496.0
If we subtract 432 from 441, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 72, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 7496.1
The remainder is 18 after subtracting 72 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
72 can be fit into 180 2 times, resulting in a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 7496.12
Subtracting 144 from 180 leaves us 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.

Going ahead to step 9:
72 can be fit into 360 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 7496.125
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 10:
0 divided by 72 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7496.125
Deduct 0 from 0 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.

On to step 11:
72 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7496.125
If we take 0 away from 0, we end up 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 outcome is 7496.125, with a leftover of 0.0.
