143413 divided by 85 
The aim is to understand the frequency of 85 in 143413.

On to step 1:
The number 85 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 85

Advancing to step 2:
85 can be fit into 14 0 times, resulting in a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 85

Advancing to step 3:
143 divided by 85 is 1 with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 85 from 143 leaves us with 58.
Bring next digit (4) of the dividend behind the 58 and repeat the process: 584 / 85

Moving on to step 4:
When dividing 584 by 85, we get 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 510 from 584, we get 74.
Fetch the next digit (1) from the dividend, attach it to 74 and continue: 741 / 85

Step 5:
When dividing 741 by 85, we get 8 with a remainder of 61.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
If we subtract 680 from 741, we get 61.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 85

Step 6:
85 goes into 613 7 times with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 1687.0
If we subtract 595 from 613, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
When dividing 180 by 85, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 1687.2
Deduct 170 from 180 and we're left 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:
85 goes into 100 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1687.21
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.

Let's proceed to step 9:
85 can be fit into 150 1 times, resulting in a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 1687.211
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 1687.211 with a remaining 0.0065.
