We divide 725831 by 72
The aim is to understand the frequency of 72 in 725831.

Advancing to step 1:
7 divided by 72 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 72

Going ahead to step 2:
The number 72 fits into 72 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 72 from 72 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 72

Let's proceed to step 3:
72 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 5 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 72

Let's proceed to step 4:
72 can be fit into 58 0 times, resulting in a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we take 0 away from 58, we end up with 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 72

Moving on to step 5:
72 can be fit into 583 8 times, resulting in a remainder of 7.
The next digit of our result is 8. 
Result so far: 1008.0
If we take 576 away from 583, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 72

Going ahead to step 6:
71 divided by 72 is 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 10080.0
If we take 0 away from 71, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 7:
72 goes into 710 9 times with a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 10080.9
If we subtract 648 from 710, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
When dividing 620 by 72, we get 8 with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 10080.98
Subtract 576 from 620 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
The number 72 fits into 440 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 10080.986
Deduct 432 from 440 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
When dividing 80 by 72, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 10080.9861
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
72 goes into 80 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 10080.98611
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 10080.98611 with a balance of 8e-06.
