We look at the division of 475839 by 85 
The aim is to understand the frequency of 85 in 475839.

Going ahead to step 1:
4 divided by 85 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 85

Let's proceed to step 2:
When dividing 47 by 85, we get 0 with a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 85

Let's proceed to step 3:
If we divide 475 by 85, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 425 from 475 and we're left with 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 85

Going ahead to step 4:
If we divide 508 by 85, we get 5 and a remainder of 83.
Use 5 as the next digit of our solution. 
Result so far: 55.0
The remainder is 83 after subtracting 425 from 508.
Grab the next digit (3) from the dividend, add it to 83, then carry on: 833 / 85

Moving on to step 5:
85 goes into 833 9 times with a remainder of 68.
Record the quotient 9 as the next digit in the result. 
Result so far: 559.0
If we subtract 765 from 833, we get 68.
Bring next digit (9) of the dividend behind the 68 and repeat the process: 689 / 85

Going ahead to step 6:
85 goes into 689 8 times with a remainder of 9.
The next digit of our result is 8. 
Result so far: 5598.0
The remainder is 9 after subtracting 680 from 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
90 divided by 85 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 5598.1
Subtract 85 from 90 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
85 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 5598.1
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
500 divided by 85 is 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 5598.105
If we take 425 away from 500, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 10:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 5598.1058
The remainder is 70 after subtracting 680 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
700 divided by 85 is 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 5598.10588
Subtracting 680 from 700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 5598.10588 and a remainder of 2e-05.
