We're dividing 764979 by 84 
The aim is to understand the frequency of 84 in 764979.

Step 1:
84 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 84

Advancing to step 2:
76 divided by 84 is 0 with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Grab the next digit (4) from the dividend, add it to 76, then carry on: 764 / 84

Moving on to step 3:
764 divided by 84 is 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 8 after subtracting 756 from 764.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 84

Advancing to step 4:
84 goes into 89 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Deduct 84 from 89 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 84

Going ahead to step 5:
84 goes into 57 0 times with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 910.0
If we subtract 0 from 57, we get 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 84

On to step 6:
84 can be fit into 579 6 times, resulting in a remainder of 75.
The next digit of our result is 6. 
Result so far: 9106.0
Subtracting 504 from 579 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 7:
84 goes into 750 8 times with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 9106.8
Subtracting 672 from 750 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 8:
780 divided by 84 is 9 with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 9106.89
Deduct 756 from 780 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.

Moving on to step 9:
When dividing 240 by 84, we get 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 9106.892
Deduct 168 from 240 and we're left 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.

Let's proceed to step 10:
84 can be fit into 720 8 times, resulting in a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 9106.8928
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 11:
84 can be fit into 480 5 times, resulting in a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 9106.89285
If we take 420 away from 480, 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.

Step 12:
When dividing 600 by 84, we get 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 9106.892857
Deduct 588 from 600 and we're left with 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 13:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 9106.8928571
If we take 84 away from 120, we end up 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 14:
When dividing 360 by 84, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 9106.89285714
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 9106.89285714 and a remainder of 2.4e-08.
