216745 ÷ 72 
The aim is to understand the frequency of 72 in 216745.

Let's proceed to step 1:
The number 72 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 72

Let's proceed to step 2:
If we divide 21 by 72, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 72

Going ahead to step 3:
The number 72 fits into 216 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 216 from 216, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 72

Advancing to step 4:
If we divide 7 by 72, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 72

Moving on to step 5:
The number 72 fits into 74 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 301.0
If we subtract 72 from 74, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 72

Step 6:
25 divided by 72 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 3010.0
If we take 0 away from 25, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
250 divided by 72 is 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 3010.3
If we subtract 216 from 250, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
72 can be fit into 340 4 times, resulting in a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 3010.34
If we subtract 288 from 340, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
72 can be fit into 520 7 times, resulting in a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 3010.347
If we subtract 504 from 520, 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.

Moving on to step 10:
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: 3010.3472
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
When dividing 160 by 72, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 3010.34722
The remainder is 16 after subtracting 144 from 160.
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 3010.34722 with a balance of 1.6e-05.
