We divide 288680 by 85
The aim is to understand the frequency of 85 in 288680.

Advancing to step 1:
If we divide 2 by 85, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 85

Going ahead to step 2:
The number 85 fits into 28 0 times, leaving a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 85

Advancing to step 3:
288 divided by 85 is 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 255 from 288, we get 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 85

Going ahead to step 4:
85 can be fit into 336 3 times, resulting in a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtracting 255 from 336 leaves us with 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 85

Let's proceed to step 5:
When dividing 818 by 85, we get 9 with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 339.0
If we subtract 765 from 818, we get 53.
Grab the next digit (0) from the dividend, add it to 53, then carry on: 530 / 85

Moving on to step 6:
If we divide 530 by 85, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 3396.0
If we take 510 away from 530, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
When dividing 200 by 85, we get 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 3396.2
Subtract 170 from 200 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
85 goes into 300 3 times with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 3396.23
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
The number 85 fits into 450 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 3396.235
Subtracting 425 from 450 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
When dividing 250 by 85, we get 2 with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 3396.2352
Subtracting 170 from 250 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
If we divide 800 by 85, we get 9 and a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 3396.23529
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
The number 85 fits into 350 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 3396.235294
If we subtract 340 from 350, we 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.

Advancing to step 13:
If we divide 100 by 85, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 3396.2352941
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.

Let's proceed to step 14:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 3396.23529411
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.

In conclusion, the division gives 3396.23529411 with a balance of 6.5e-08.
