38979 ÷ 72 
The aim is to understand the frequency of 72 in 38979.

Step 1:
3 divided by 72 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 72

Let's proceed to step 2:
72 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 72

On to step 3:
72 can be fit into 389 5 times, resulting in a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 360 away from 389, we end up with 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 72

Going ahead to step 4:
The number 72 fits into 297 4 times, leaving a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
If we subtract 288 from 297, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 72

Moving on to step 5:
99 divided by 72 is 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 541.0
Subtracting 72 from 99 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 6:
The number 72 fits into 270 3 times, leaving a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 541.3
Deduct 216 from 270 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
When dividing 540 by 72, we get 7 with a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 541.37
If we subtract 504 from 540, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
360 divided by 72 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 541.375
If we subtract 360 from 360, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 72 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 541.375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 72 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 541.375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 541.375 with a remainder of 0.0.
