We're dividing 453255 by 85 
The aim is to understand the frequency of 85 in 453255.

Step 1:
The number 85 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 85

Advancing to step 2:
85 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 85

Going ahead to step 3:
When dividing 453 by 85, we get 5 with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 425 from 453 to get 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 85

Step 4:
The number 85 fits into 282 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we take 255 away from 282, we end up with 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 85

Let's proceed to step 5:
When dividing 275 by 85, we get 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 533.0
Deduct 255 from 275 and we're left with 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 85

Advancing to step 6:
When dividing 205 by 85, we get 2 with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 5332.0
Deduct 170 from 205 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
350 divided by 85 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 5332.4
Subtract 340 from 350 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 85, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 5332.41
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
If we divide 150 by 85, we get 1 and a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 5332.411
Subtracting 85 from 150 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 5332.411, and the remainder is 0.0065.
