We look at the division of 957938 by 72 
The aim is to understand the frequency of 72 in 957938.

Moving on to step 1:
72 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 72

Going ahead to step 2:
72 goes into 95 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 72 from 95 to get 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 72

Going ahead to step 3:
When dividing 237 by 72, we get 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 216 from 237 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 72

Moving on to step 4:
The number 72 fits into 219 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 133.0
If we take 216 away from 219, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 72

Advancing to step 5:
If we divide 33 by 72, we get 0 and a remainder of 33.
The next digit of our result is 0. 
Result so far: 1330.0
Subtracting 0 from 33 leaves us with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 72

Let's proceed to step 6:
The number 72 fits into 338 4 times, leaving a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 13304.0
If we subtract 288 from 338, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
When dividing 500 by 72, we get 6 with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 13304.6
Deduct 432 from 500 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
680 divided by 72 is 9 with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 13304.69
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
72 goes into 320 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 13304.694
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
If we divide 320 by 72, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 13304.6944
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 13304.6944, with a leftover of 0.00032.
