We're dividing 900593 by 85 
The aim is to understand the frequency of 85 in 900593.

Moving on to step 1:
85 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 85

Step 2:
If we divide 90 by 85, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 85 from 90, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 85

Let's proceed to step 3:
85 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 50 after subtracting 0 from 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 85

Going ahead to step 4:
The number 85 fits into 505 5 times, leaving a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Subtract 425 from 505 to get 80.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 85

Let's proceed to step 5:
If we divide 809 by 85, we get 9 and a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 1059.0
If we take 765 away from 809, we end up with 44.
Fetch the next digit (3) from the dividend, attach it to 44 and continue: 443 / 85

Step 6:
When dividing 443 by 85, we get 5 with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 10595.0
Deduct 425 from 443 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
When dividing 180 by 85, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 10595.2
Subtracting 170 from 180 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 85, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 10595.21
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
150 divided by 85 is 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 10595.211
If we subtract 85 from 150, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 10595.211, with a leftover of 0.0065.
