We're dividing 622806 by 84 
The aim is to understand the frequency of 84 in 622806.

Going ahead to step 1:
When dividing 6 by 84, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 84

Moving on to step 2:
When dividing 62 by 84, we get 0 with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Bring next digit (2) of the dividend behind the 62 and repeat the process: 622 / 84

Going ahead to step 3:
84 goes into 622 7 times with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 588 away from 622, we end up with 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 84

Moving on to step 4:
If we divide 348 by 84, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Deduct 336 from 348 and we're left with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 84

On to step 5:
When dividing 120 by 84, we get 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 741.0
The remainder is 36 after subtracting 84 from 120.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 84

Moving on to step 6:
The number 84 fits into 366 4 times, leaving a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 7414.0
Subtracting 336 from 366 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
If we divide 300 by 84, we get 3 and a remainder of 48.
The next digit of our result is 3. 
Result so far: 7414.3
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.

Step 8:
When dividing 480 by 84, we get 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 7414.35
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 7414.357
If we subtract 588 from 600, we 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.

On to step 10:
120 divided by 84 is 1 with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 7414.3571
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 7414.35714
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.

Going ahead to step 12:
The number 84 fits into 240 2 times, leaving a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 7414.357142
Subtract 168 from 240 to 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.

Let's proceed to step 13:
When dividing 720 by 84, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 7414.3571428
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.

Advancing to step 14:
The number 84 fits into 480 5 times, leaving a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 7414.35714285
Deduct 420 from 480 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 7414.35714285 with a remainder of 6e-08.
