We divide 857132 by 72
The aim is to understand the frequency of 72 in 857132.

Let's proceed to step 1:
8 divided by 72 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 72

Step 2:
If we divide 85 by 72, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 72 from 85 to get 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 72

Moving on to step 3:
137 divided by 72 is 1 with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 72 from 137 and we're left with 65.
Append the next digit (1) from the dividend to 65 and continue with: 651 / 72

Let's proceed to step 4:
The number 72 fits into 651 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Subtracting 648 from 651 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 72

Let's proceed to step 5:
The number 72 fits into 33 0 times, leaving a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 1190.0
If we subtract 0 from 33, we get 33.
Append the next digit (2) from the dividend to 33 and continue with: 332 / 72

Step 6:
332 divided by 72 is 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 11904.0
Deduct 288 from 332 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
If we divide 440 by 72, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 11904.6
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
When dividing 80 by 72, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 11904.61
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
When dividing 80 by 72, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 11904.611
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 11904.611, with a leftover of 0.0008.
