We look at the division of 693843 by 84 
The aim is to understand the frequency of 84 in 693843.

On to step 1:
If we divide 6 by 84, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 84

On to step 2:
The number 84 fits into 69 0 times, leaving a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 84

Moving on to step 3:
84 can be fit into 693 8 times, resulting in a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 672 from 693, we get 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 84

Step 4:
84 goes into 218 2 times with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtracting 168 from 218 leaves us with 50.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 84

Going ahead to step 5:
84 goes into 504 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 826.0
If we subtract 504 from 504, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 84

Going ahead to step 6:
84 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 8260.0
Deduct 0 from 3 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
84 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 8260.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 84, we get 3 and a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 8260.03
Deduct 252 from 300 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
84 goes into 480 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 8260.035
If we subtract 420 from 480, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
If we divide 600 by 84, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 8260.0357
Subtract 588 from 600 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
84 goes into 120 1 times with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 8260.03571
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
84 can be fit into 360 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 8260.035714
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
The number 84 fits into 240 2 times, leaving a remainder of 72.
The next digit of our result is 2. 
Result so far: 8260.0357142
If we subtract 168 from 240, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
84 can be fit into 720 8 times, resulting in a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 8260.03571428
Deduct 672 from 720 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 8260.03571428 with a remaining 4.8e-08.
