We divide 62440 by 72
The aim is to understand the frequency of 72 in 62440.

On to step 1:
6 divided by 72 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 72

Let's proceed to step 2:
72 goes into 62 0 times with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Grab the next digit (4) from the dividend, add it to 62, then carry on: 624 / 72

Let's proceed to step 3:
When dividing 624 by 72, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 576 away from 624, we end up with 48.
Bring next digit (4) of the dividend behind the 48 and repeat the process: 484 / 72

On to step 4:
72 goes into 484 6 times with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Deduct 432 from 484 and we're left with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 72

On to step 5:
72 goes into 520 7 times with a remainder of 16.
The next digit of our result is 7. 
Result so far: 867.0
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 6:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 867.2
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 72, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 867.22
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 867.22 with a remaining 0.016.
