We look at the division of 376977 by 72 
The aim is to understand the frequency of 72 in 376977.

Advancing to step 1:
3 divided by 72 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 72

Step 2:
The number 72 fits into 37 0 times, leaving a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 72

Let's proceed to step 3:
When dividing 376 by 72, we get 5 with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 360 away from 376, we end up with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 72

On to step 4:
If we divide 169 by 72, we get 2 and a remainder of 25.
The next digit of our result is 2. 
Result so far: 52.0
If we subtract 144 from 169, we get 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 72

Step 5:
If we divide 257 by 72, we get 3 and a remainder of 41.
The next digit of our result is 3. 
Result so far: 523.0
Deduct 216 from 257 and we're left with 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 72

Let's proceed to step 6:
72 can be fit into 417 5 times, resulting in a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 5235.0
Subtract 360 from 417 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
When dividing 570 by 72, we get 7 with a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 5235.7
The remainder is 66 after subtracting 504 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 8:
72 can be fit into 660 9 times, resulting in a remainder of 12.
The next digit of our result is 9. 
Result so far: 5235.79
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
120 divided by 72 is 1 with a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 5235.791
If we take 72 away from 120, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
The number 72 fits into 480 6 times, leaving a remainder of 48.
The next digit of our result is 6. 
Result so far: 5235.7916
If we subtract 432 from 480, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
72 can be fit into 480 6 times, resulting in a remainder of 48.
The next digit of our result is 6. 
Result so far: 5235.79166
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 5235.79166 with a remainder of 4.8e-05.
