We're dividing 853109 by 85 
The aim is to understand the frequency of 85 in 853109.

On to step 1:
85 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 85

On to step 2:
If we divide 85 by 85, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 85 from 85 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 85

Step 3:
85 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 85

Step 4:
The number 85 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 100.0
If we take 0 away from 31, we end up with 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 85

Going ahead to step 5:
85 goes into 310 3 times with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 1003.0
Deduct 255 from 310 and we're left with 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 85

Moving on to step 6:
The number 85 fits into 559 6 times, leaving a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 10036.0
The remainder is 49 after subtracting 510 from 559.
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 can be fit into 490 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 10036.5
The remainder is 65 after subtracting 425 from 490.
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:
If we divide 650 by 85, we get 7 and a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 10036.57
Subtract 595 from 650 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 9:
If we divide 550 by 85, we get 6 and a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 10036.576
If we take 510 away from 550, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 85 is 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 10036.5764
The remainder is 60 after subtracting 340 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
When dividing 600 by 85, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 10036.57647
Subtract 595 from 600 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.

Going ahead to step 12:
50 divided by 85 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10036.57647
If we subtract 0 from 50, we 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 13:
500 divided by 85 is 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 10036.5764705
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 14:
85 goes into 750 8 times with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 10036.57647058
Subtracting 680 from 750 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 10036.57647058, and the remainder is 7e-08.
