We look at the division of 72141132 by 85 
The aim is to understand the frequency of 85 in 72141132.

Going ahead to step 1:
85 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 85

Let's proceed to step 2:
The number 85 fits into 72 0 times, leaving a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 85

Let's proceed to step 3:
85 goes into 721 8 times with a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 680 away from 721, we end up with 41.
Take the next digit (4) from the dividend and append it to 41, then repeat: 414 / 85

Step 4:
85 goes into 414 4 times with a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Deduct 340 from 414 and we're left with 74.
Append the next digit (1) from the dividend to 74 and continue with: 741 / 85

Going ahead to step 5:
741 divided by 85 is 8 with a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 848.0
If we subtract 680 from 741, we get 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 85

Step 6:
85 can be fit into 611 7 times, resulting in a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 8487.0
Deduct 595 from 611 and we're left with 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 85

Advancing to step 7:
85 goes into 163 1 times with a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 84871.0
The remainder is 78 after subtracting 85 from 163.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 85

On to step 8:
782 divided by 85 is 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 848719.0
Subtract 765 from 782 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
The number 85 fits into 170 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 848719.2
The remainder is 0 after subtracting 170 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 85 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 848719.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 85 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 848719.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 848719.2, and the remainder is 0.0.
