120685 divided by 72 
The aim is to understand the frequency of 72 in 120685.

On to step 1:
1 divided by 72 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 72

On to step 2:
The number 72 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 72

Step 3:
When dividing 120 by 72, we get 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 72 away from 120, we end up with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 72

On to step 4:
72 goes into 486 6 times with a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 432 from 486 leaves us with 54.
Append the next digit (8) from the dividend to 54 and continue with: 548 / 72

Advancing to step 5:
When dividing 548 by 72, we get 7 with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
If we subtract 504 from 548, we get 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 72

Let's proceed to step 6:
72 goes into 445 6 times with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 1676.0
If we take 432 away from 445, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
72 can be fit into 130 1 times, resulting in a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 1676.1
If we subtract 72 from 130, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 8:
When dividing 580 by 72, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 1676.18
If we subtract 576 from 580, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 72, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1676.18
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 72, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 1676.1805
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
The number 72 fits into 400 5 times, leaving a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 1676.18055
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 1676.18055 with a remainder of 4e-05.
