Let's divide 28575669 by 85
The aim is to understand the frequency of 85 in 28575669.

Moving on to step 1:
2 divided by 85 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 85

On to step 2:
85 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 85

Let's proceed to step 3:
If we divide 285 by 85, we get 3 and a remainder of 30.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 30 after subtracting 255 from 285.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 85

Going ahead to step 4:
If we divide 307 by 85, we get 3 and a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Deduct 255 from 307 and we're left with 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 85

Let's proceed to step 5:
When dividing 525 by 85, we get 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 336.0
Subtract 510 from 525 to get 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 85

Moving on to step 6:
85 goes into 156 1 times with a remainder of 71.
The next digit of our result is 1. 
Result so far: 3361.0
Deduct 85 from 156 and we're left with 71.
Take the next digit (6) from the dividend and append it to 71, then repeat: 716 / 85

Advancing to step 7:
If we divide 716 by 85, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 33618.0
Deduct 680 from 716 and we're left with 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 85

Let's proceed to step 8:
369 divided by 85 is 4 with a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 336184.0
Deduct 340 from 369 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
When dividing 290 by 85, we get 3 with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 336184.3
Subtracting 255 from 290 leaves us 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.

Advancing to step 10:
85 can be fit into 350 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 336184.34
Deduct 340 from 350 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.

Step 11:
100 divided by 85 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 336184.341
Subtract 85 from 100 to 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 12:
If we divide 150 by 85, we get 1 and a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 336184.3411
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 336184.3411, and the remainder is 0.00065.
