We're dividing 682945 by 84 
The aim is to understand the frequency of 84 in 682945.

Advancing to step 1:
When dividing 6 by 84, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 84

Moving on to step 2:
68 divided by 84 is 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Take the next digit (2) from the dividend and append it to 68, then repeat: 682 / 84

Let's proceed to step 3:
When dividing 682 by 84, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 672 from 682 to get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 84

On to step 4:
The number 84 fits into 109 1 times, leaving a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we take 84 away from 109, we end up with 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 84

Let's proceed to step 5:
84 can be fit into 254 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 813.0
Subtract 252 from 254 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 84

Going ahead to step 6:
25 divided by 84 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 8130.0
If we take 0 away from 25, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
250 divided by 84 is 2 with a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 8130.2
Subtracting 168 from 250 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 8:
When dividing 820 by 84, we get 9 with a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 8130.29
If we subtract 756 from 820, we 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.

Let's proceed to step 9:
When dividing 640 by 84, we get 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 8130.297
Deduct 588 from 640 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
520 divided by 84 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 8130.2976
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 84 fits into 160 1 times, leaving a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 8130.29761
Subtract 84 from 160 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
If we divide 760 by 84, we get 9 and a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 8130.297619
Subtract 756 from 760 to get 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 13:
If we divide 40 by 84, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8130.297619
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
84 goes into 400 4 times with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 8130.29761904
Deduct 336 from 400 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 8130.29761904 with a remainder of 6.4e-08.
