812475 divided by 84 
The aim is to understand the frequency of 84 in 812475.

Advancing to step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 84

On to step 2:
84 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 84

Moving on to step 3:
When dividing 812 by 84, we get 9 with a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 756 from 812, we get 56.
Fetch the next digit (4) from the dividend, attach it to 56 and continue: 564 / 84

On to step 4:
84 goes into 564 6 times with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 96.0
The remainder is 60 after subtracting 504 from 564.
Fetch the next digit (7) from the dividend, attach it to 60 and continue: 607 / 84

Going ahead to step 5:
When dividing 607 by 84, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 967.0
If we subtract 588 from 607, we get 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 84

Advancing to step 6:
84 can be fit into 195 2 times, resulting in a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 9672.0
The remainder is 27 after subtracting 168 from 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
84 can be fit into 270 3 times, resulting in a remainder of 18.
The next digit of our result is 3. 
Result so far: 9672.3
If we take 252 away from 270, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
84 goes into 180 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 9672.32
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 9672.321
If we subtract 84 from 120, we 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.

Moving on to step 10:
360 divided by 84 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 9672.3214
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
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: 9672.32142
The remainder is 72 after subtracting 168 from 240.
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 12:
The number 84 fits into 720 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 9672.321428
Subtract 672 from 720 to 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.

Let's proceed to step 13:
84 goes into 480 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 9672.3214285
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.

Advancing to step 14:
600 divided by 84 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 9672.32142857
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.

The quotient of the division is 9672.32142857, and the remainder is 1.2e-08.
