Let's divide 212830 by 72
The aim is to understand the frequency of 72 in 212830.

Let's proceed to step 1:
2 divided by 72 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 72

Let's proceed to step 2:
72 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 72

Advancing to step 3:
212 divided by 72 is 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 68 after subtracting 144 from 212.
Grab the next digit (8) from the dividend, add it to 68, then carry on: 688 / 72

Going ahead to step 4:
72 can be fit into 688 9 times, resulting in a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 648 from 688 leaves us with 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 72

Advancing to step 5:
403 divided by 72 is 5 with a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 295.0
If we take 360 away from 403, we end up with 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 72

On to step 6:
The number 72 fits into 430 5 times, leaving a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 2955.0
Deduct 360 from 430 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 7:
700 divided by 72 is 9 with a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 2955.9
Subtracting 648 from 700 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 8:
When dividing 520 by 72, we get 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 2955.97
Subtracting 504 from 520 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
160 divided by 72 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2955.972
Subtracting 144 from 160 leaves us with 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 10:
160 divided by 72 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2955.9722
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.

In conclusion, the division gives 2955.9722 with a balance of 0.00016.
