228021 divided by 72 
The aim is to understand the frequency of 72 in 228021.

Let's proceed to step 1:
When dividing 2 by 72, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 72

Advancing to step 2:
72 goes into 22 0 times with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 72

Advancing to step 3:
72 can be fit into 228 3 times, resulting in a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 216 from 228 and we're left with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 72

Let's proceed to step 4:
72 goes into 120 1 times with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we take 72 away from 120, we end up with 48.
Grab the next digit (2) from the dividend, add it to 48, then carry on: 482 / 72

Going ahead to step 5:
If we divide 482 by 72, we get 6 and a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 316.0
If we subtract 432 from 482, we get 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 72

Moving on to step 6:
The number 72 fits into 501 6 times, leaving a remainder of 69.
Use 6 as the next digit of our solution. 
Result so far: 3166.0
Deduct 432 from 501 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
The number 72 fits into 690 9 times, leaving a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 3166.9
If we take 648 away from 690, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
72 can be fit into 420 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 3166.95
Deduct 360 from 420 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
72 can be fit into 600 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 3166.958
Deduct 576 from 600 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
72 goes into 240 3 times with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 3166.9583
If we subtract 216 from 240, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
72 goes into 240 3 times with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 3166.95833
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 3166.95833 with a balance of 2.4e-05.
