Let's divide 278187 by 85
The aim is to understand the frequency of 85 in 278187.

Advancing to step 1:
85 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 85

Moving on to step 2:
When dividing 27 by 85, we get 0 with a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 85

Step 3:
85 goes into 278 3 times with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 255 from 278 leaves us with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 85

Moving on to step 4:
85 goes into 231 2 times with a remainder of 61.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Deduct 170 from 231 and we're left with 61.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 85

Moving on to step 5:
618 divided by 85 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 327.0
Subtracting 595 from 618 leaves us with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 85

Moving on to step 6:
When dividing 237 by 85, we get 2 with a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 3272.0
If we subtract 170 from 237, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 7:
The number 85 fits into 670 7 times, leaving a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 3272.7
The remainder is 75 after subtracting 595 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 8:
The number 85 fits into 750 8 times, leaving a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 3272.78
If we subtract 680 from 750, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
If we divide 700 by 85, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 3272.788
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.

The final outcome is 3272.788, with a leftover of 0.002.
