We look at the division of 265178 by 84 
The aim is to understand the frequency of 84 in 265178.

Going ahead to step 1:
The number 84 fits into 2 0 times, leaving 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 (6) from the dividend, add it to 2, then carry on: 26 / 84

Let's proceed to step 2:
26 divided by 84 is 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 84

Moving on to step 3:
265 divided by 84 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 252 from 265, we get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 84

On to step 4:
84 goes into 131 1 times with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtract 84 from 131 to get 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 84

Going ahead to step 5:
The number 84 fits into 477 5 times, leaving a remainder of 57.
Record the quotient 5 as the next digit in the result. 
Result so far: 315.0
Subtract 420 from 477 to get 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 84

Step 6:
84 goes into 578 6 times with a remainder of 74.
The next digit of our result is 6. 
Result so far: 3156.0
If we subtract 504 from 578, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 7:
The number 84 fits into 740 8 times, leaving a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 3156.8
Subtracting 672 from 740 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
When dividing 680 by 84, we get 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 3156.88
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 3156.88, and the remainder is 0.008.
