We're dividing 770530 by 84 
The aim is to understand the frequency of 84 in 770530.

Step 1:
The number 84 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 84

Going ahead to step 2:
When dividing 77 by 84, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Append the next digit (0) from the dividend to 77 and continue with: 770 / 84

Step 3:
If we divide 770 by 84, we get 9 and a remainder of 14.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 756 from 770 leaves us with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 84

Step 4:
84 can be fit into 145 1 times, resulting in a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we subtract 84 from 145, we get 61.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 84

Going ahead to step 5:
If we divide 613 by 84, we get 7 and a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 917.0
If we take 588 away from 613, we end up with 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 84

Advancing to step 6:
250 divided by 84 is 2 with a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 9172.0
If we subtract 168 from 250, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 7:
If we divide 820 by 84, we get 9 and a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 9172.9
Deduct 756 from 820 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.

Let's proceed to step 8:
The number 84 fits into 640 7 times, leaving a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 9172.97
Subtracting 588 from 640 leaves us 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 9:
The number 84 fits into 520 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 9172.976
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 84 fits into 160 1 times, leaving a remainder of 76.
The next digit of our result is 1. 
Result so far: 9172.9761
The remainder is 76 after subtracting 84 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
84 goes into 760 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9172.97619
If we subtract 756 from 760, we 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.

Step 12:
If we divide 40 by 84, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 9172.97619
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
The number 84 fits into 400 4 times, leaving a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 9172.9761904
If we take 336 away from 400, we end up 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.

Moving on to step 14:
If we divide 640 by 84, we get 7 and a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 9172.97619047
Subtracting 588 from 640 leaves us 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.

In conclusion, the division gives 9172.97619047 with a balance of 5.2e-08.
