We're dividing 835876 by 84 
The aim is to understand the frequency of 84 in 835876.

Moving on to step 1:
84 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 84

Advancing to step 2:
If we divide 83 by 84, we get 0 and a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Grab the next digit (5) from the dividend, add it to 83, then carry on: 835 / 84

Let's proceed to step 3:
When dividing 835 by 84, we get 9 with a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 756 from 835 leaves us with 79.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 84

Advancing to step 4:
When dividing 798 by 84, we get 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we subtract 756 from 798, we get 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 84

Step 5:
When dividing 427 by 84, we get 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 995.0
Subtracting 420 from 427 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 84

Going ahead to step 6:
The number 84 fits into 76 0 times, leaving a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 9950.0
If we take 0 away from 76, we end up 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.

Going ahead to step 7:
84 can be fit into 760 9 times, resulting in a remainder of 4.
The next digit of our result is 9. 
Result so far: 9950.9
Deduct 756 from 760 and we're left 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 8:
When dividing 40 by 84, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 9950.9
Deduct 0 from 40 and we're left 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.

Step 9:
400 divided by 84 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 9950.904
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.

On to step 10:
The number 84 fits into 640 7 times, leaving a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 9950.9047
The remainder is 52 after subtracting 588 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
520 divided by 84 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 9950.90476
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
84 can be fit into 160 1 times, resulting in a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 9950.904761
Subtracting 84 from 160 leaves us 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.

On 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: 9950.9047619
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.

Moving on to step 14:
84 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9950.9047619
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.

Our division results in 9950.9047619 with a remaining 4e-08.
