We divide 673288 by 72
The aim is to understand the frequency of 72 in 673288.

Going ahead to step 1:
72 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 72

Moving on to step 2:
72 can be fit into 67 0 times, resulting in a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Fetch the next digit (3) from the dividend, attach it to 67 and continue: 673 / 72

Advancing to step 3:
72 can be fit into 673 9 times, resulting in a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 648 from 673 to get 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 72

On to step 4:
The number 72 fits into 252 3 times, leaving a remainder of 36.
The next digit of our result is 3. 
Result so far: 93.0
Deduct 216 from 252 and we're left with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 72

Moving on to step 5:
The number 72 fits into 368 5 times, leaving a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 935.0
If we take 360 away from 368, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 72

Going ahead to step 6:
When dividing 88 by 72, we get 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 9351.0
If we subtract 72 from 88, 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.

Let's proceed to step 7:
72 goes into 160 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 9351.2
Subtracting 144 from 160 leaves us 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 8:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 9351.22
Subtracting 144 from 160 leaves us 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.

Our division results in 9351.22 with a remaining 0.016.
