809181 divided by 84 
The aim is to understand the frequency of 84 in 809181.

Step 1:
If we divide 8 by 84, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 84

Let's proceed to step 2:
84 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 84

Step 3:
When dividing 809 by 84, we get 9 with a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 756 away from 809, we end up with 53.
Include the next digit (1) from the dividend after 53, then repeat: 531 / 84

Let's proceed to step 4:
When dividing 531 by 84, we get 6 with a remainder of 27.
The next digit of our result is 6. 
Result so far: 96.0
Subtract 504 from 531 to get 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 84

Going ahead to step 5:
If we divide 278 by 84, we get 3 and a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 963.0
Subtract 252 from 278 to get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 84

Let's proceed to step 6:
84 goes into 261 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 9633.0
Subtract 252 from 261 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
84 can be fit into 90 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 9633.1
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
84 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 9633.1
If we take 0 away from 60, we end up 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.

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: 9633.107
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.

Going ahead to step 10:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 9633.1071
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.

Moving on to step 11:
The number 84 fits into 360 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 9633.10714
If we take 336 away from 360, we end up 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:
84 goes into 240 2 times with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 9633.107142
Subtracting 168 from 240 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
84 goes into 720 8 times with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 9633.1071428
If we subtract 672 from 720, we get 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:
480 divided by 84 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 9633.10714285
Subtracting 420 from 480 leaves us 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.

After the division, we end up with 9633.10714285 and a remainder of 6e-08.
