We look at the division of 738971 by 85 
The aim is to understand the frequency of 85 in 738971.

Let's proceed to step 1:
85 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 85

Moving on to step 2:
85 can be fit into 73 0 times, resulting in a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 85

Step 3:
When dividing 738 by 85, we get 8 with a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 680 away from 738, we end up with 58.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 85

Advancing to step 4:
85 can be fit into 589 6 times, resulting in a remainder of 79.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
The remainder is 79 after subtracting 510 from 589.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 85

Step 5:
797 divided by 85 is 9 with a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 869.0
If we subtract 765 from 797, we get 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 85

Step 6:
85 goes into 321 3 times with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 8693.0
If we subtract 255 from 321, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
85 can be fit into 660 7 times, resulting in a remainder of 65.
The next digit of our result is 7. 
Result so far: 8693.7
If we take 595 away from 660, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 8:
650 divided by 85 is 7 with a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 8693.77
Subtracting 595 from 650 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 8693.77 with a remaining 0.055.
