We're dividing 835357 by 84 
The aim is to understand the frequency of 84 in 835357.

Going ahead to step 1:
The number 84 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 84

On to step 2:
84 goes into 83 0 times with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Take the next digit (5) from the dividend and append it to 83, then repeat: 835 / 84

On to step 3:
835 divided by 84 is 9 with a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 756 from 835, we get 79.
Take the next digit (3) from the dividend and append it to 79, then repeat: 793 / 84

Moving on to step 4:
If we divide 793 by 84, we get 9 and a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we take 756 away from 793, we end up with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 84

Let's proceed to step 5:
When dividing 375 by 84, we get 4 with a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 994.0
Subtract 336 from 375 to get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 84

Moving on to step 6:
When dividing 397 by 84, we get 4 with a remainder of 61.
Put 4 as the next digit of the answer. 
Result so far: 9944.0
Deduct 336 from 397 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 7:
84 can be fit into 610 7 times, resulting in a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 9944.7
The remainder is 22 after subtracting 588 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
220 divided by 84 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 9944.72
The remainder is 52 after subtracting 168 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
The number 84 fits into 520 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 9944.726
The remainder is 16 after subtracting 504 from 520.
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 10:
160 divided by 84 is 1 with a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 9944.7261
The remainder is 76 after subtracting 84 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
84 can be fit into 760 9 times, resulting in a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9944.72619
Subtract 756 from 760 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
The number 84 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 9944.72619
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.

Moving on to step 13:
84 goes into 400 4 times with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 9944.7261904
Subtract 336 from 400 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
640 divided by 84 is 7 with a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 9944.72619047
If we subtract 588 from 640, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 9944.72619047, and the remainder is 5.2e-08.
