We look at the division of 448934 by 85 
The aim is to understand the frequency of 85 in 448934.

Going ahead to step 1:
When dividing 4 by 85, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 85

Step 2:
44 divided by 85 is 0 with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Include the next digit (8) from the dividend after 44, then repeat: 448 / 85

Advancing to step 3:
85 goes into 448 5 times with a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 425 from 448 to get 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 85

Moving on to step 4:
The number 85 fits into 239 2 times, leaving a remainder of 69.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
The remainder is 69 after subtracting 170 from 239.
Include the next digit (3) from the dividend after 69, then repeat: 693 / 85

Advancing to step 5:
85 goes into 693 8 times with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 528.0
Subtract 680 from 693 to get 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 85

On to step 6:
If we divide 134 by 85, we get 1 and a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 5281.0
If we take 85 away from 134, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
85 goes into 490 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 5281.5
Subtract 425 from 490 to 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.

Advancing to step 8:
When dividing 650 by 85, we get 7 with a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 5281.57
If we take 595 away from 650, we end up 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.

Moving on to step 9:
85 goes into 550 6 times with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 5281.576
The remainder is 40 after subtracting 510 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
The number 85 fits into 400 4 times, leaving a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 5281.5764
Deduct 340 from 400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
The number 85 fits into 600 7 times, leaving a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 5281.57647
The remainder is 5 after subtracting 595 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
85 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 5281.57647
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.

Advancing to step 13:
When dividing 500 by 85, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 5281.5764705
Subtracting 425 from 500 leaves us 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.

On to step 14:
85 can be fit into 750 8 times, resulting in a remainder of 70.
The next digit of our result is 8. 
Result so far: 5281.57647058
If we subtract 680 from 750, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 5281.57647058 with a remaining 7e-08.
