Let's divide 877595 by 84
The aim is to understand the frequency of 84 in 877595.

Advancing to step 1:
The number 84 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 84

On to step 2:
The number 84 fits into 87 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 84 from 87 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 84

Step 3:
84 goes into 37 0 times with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 37 to get 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 84

Going ahead to step 4:
375 divided by 84 is 4 with a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Subtract 336 from 375 to get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 84

Going ahead to step 5:
If we divide 399 by 84, we get 4 and a remainder of 63.
The next digit of our result is 4. 
Result so far: 1044.0
Subtracting 336 from 399 leaves us with 63.
Append the next digit (5) from the dividend to 63 and continue with: 635 / 84

Moving on to step 6:
When dividing 635 by 84, we get 7 with a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 10447.0
If we subtract 588 from 635, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
470 divided by 84 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 10447.5
If we subtract 420 from 470, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
The number 84 fits into 500 5 times, leaving a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 10447.55
If we take 420 away from 500, we end up 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.

The final outcome is 10447.55, with a leftover of 0.08.
