We divide 809599 by 85
The aim is to understand the frequency of 85 in 809599.

On to step 1:
When dividing 8 by 85, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 85

Let's proceed to step 2:
The number 85 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 85

Going ahead to step 3:
809 divided by 85 is 9 with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 765 from 809, we get 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 85

On to step 4:
445 divided by 85 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Deduct 425 from 445 and we're left with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 85

Going ahead to step 5:
85 can be fit into 209 2 times, resulting in a remainder of 39.
The next digit of our result is 2. 
Result so far: 952.0
If we take 170 away from 209, we end up with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 85

Moving on to step 6:
85 goes into 399 4 times with a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 9524.0
Subtracting 340 from 399 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
85 goes into 590 6 times with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 9524.6
Deduct 510 from 590 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 8:
85 can be fit into 800 9 times, resulting in a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 9524.69
If we take 765 away from 800, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
When dividing 350 by 85, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 9524.694
The remainder is 10 after subtracting 340 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
When dividing 100 by 85, we get 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 9524.6941
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
85 goes into 150 1 times with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 9524.69411
The remainder is 65 after subtracting 85 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 9524.69411 with a remaining 6.5e-05.
