We divide 454970 by 85
The aim is to understand the frequency of 85 in 454970.

Advancing to step 1:
4 divided by 85 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 85

Going ahead to step 2:
45 divided by 85 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (4) from the dividend to 45 and continue with: 454 / 85

Moving on to step 3:
The number 85 fits into 454 5 times, leaving a remainder of 29.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 425 from 454 to get 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 85

Going ahead to step 4:
85 can be fit into 299 3 times, resulting in a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Deduct 255 from 299 and we're left with 44.
Take the next digit (7) from the dividend and append it to 44, then repeat: 447 / 85

Let's proceed to step 5:
447 divided by 85 is 5 with a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 535.0
Subtract 425 from 447 to get 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 85

Moving on to step 6:
220 divided by 85 is 2 with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 5352.0
The remainder is 50 after subtracting 170 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
If we divide 500 by 85, we get 5 and a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 5352.5
The remainder is 75 after subtracting 425 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 8:
85 goes into 750 8 times with a remainder of 70.
The next digit of our result is 8. 
Result so far: 5352.58
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.

Step 9:
The number 85 fits into 700 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 5352.588
The remainder is 20 after subtracting 680 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 5352.588 with a remainder of 0.002.
