We look at the division of 854608 by 84 
The aim is to understand the frequency of 84 in 854608.

Step 1:
84 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 84

Going ahead to step 2:
When dividing 85 by 84, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 84 from 85 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 84

Let's proceed to step 3:
14 divided by 84 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 14 after subtracting 0 from 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 84

On to step 4:
If we divide 146 by 84, we get 1 and a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
If we take 84 away from 146, we end up with 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 84

Moving on to step 5:
620 divided by 84 is 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 1017.0
If we subtract 588 from 620, we get 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 84

Going ahead to step 6:
The number 84 fits into 328 3 times, leaving a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 10173.0
If we subtract 252 from 328, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 7:
The number 84 fits into 760 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 10173.9
Subtracting 756 from 760 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
84 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10173.9
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
84 goes into 400 4 times with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 10173.904
If we take 336 away from 400, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
84 goes into 640 7 times with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 10173.9047
Subtracting 588 from 640 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
If we divide 520 by 84, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 10173.90476
Subtract 504 from 520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
If we divide 160 by 84, we get 1 and a remainder of 76.
The next digit of our result is 1. 
Result so far: 10173.904761
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 13:
The number 84 fits into 760 9 times, leaving a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 10173.9047619
Subtracting 756 from 760 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
When dividing 40 by 84, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10173.9047619
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 10173.9047619, and the remainder is 4e-08.
