424512 divided by 85 
The aim is to understand the frequency of 85 in 424512.

Advancing to step 1:
If we divide 4 by 85, we get 0 and 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.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 85

Let's proceed to step 2:
If we divide 42 by 85, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 85

Let's proceed to step 3:
85 goes into 424 4 times with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 340 from 424 and we're left with 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 85

Moving on to step 4:
If we divide 845 by 85, we get 9 and a remainder of 80.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtracting 765 from 845 leaves us with 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 85

On to step 5:
The number 85 fits into 801 9 times, leaving a remainder of 36.
The next digit of our result is 9. 
Result so far: 499.0
The remainder is 36 after subtracting 765 from 801.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 85

Going ahead to step 6:
When dividing 362 by 85, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 4994.0
If we take 340 away from 362, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
85 can be fit into 220 2 times, resulting in a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 4994.2
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.

Moving on to step 8:
500 divided by 85 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 4994.25
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 9:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 4994.258
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.

Let's proceed to step 10:
The number 85 fits into 700 8 times, leaving a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 4994.2588
Subtract 680 from 700 to get 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 4994.2588 and a remainder of 0.0002.
