667852 divided by 72 
The aim is to understand the frequency of 72 in 667852.

Advancing to step 1:
When dividing 6 by 72, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 72

Step 2:
When dividing 66 by 72, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (7) from the dividend, add it to 66, then carry on: 667 / 72

Moving on to step 3:
When dividing 667 by 72, we get 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 648 away from 667, we end up with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 72

Moving on to step 4:
When dividing 198 by 72, we get 2 with a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 92.0
Subtract 144 from 198 to get 54.
Fetch the next digit (5) from the dividend, attach it to 54 and continue: 545 / 72

Moving on to step 5:
72 goes into 545 7 times with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 927.0
Subtract 504 from 545 to get 41.
Include the next digit (2) from the dividend after 41, then repeat: 412 / 72

Moving on to step 6:
72 can be fit into 412 5 times, resulting in a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 9275.0
Deduct 360 from 412 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 7:
72 can be fit into 520 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 9275.7
The remainder is 16 after subtracting 504 from 520.
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 8:
160 divided by 72 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 9275.72
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
When dividing 160 by 72, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 9275.722
Subtract 144 from 160 to 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.

The quotient of the division is 9275.722, and the remainder is 0.0016.
