We're dividing 791890 by 84 
The aim is to understand the frequency of 84 in 791890.

Advancing to step 1:
If we divide 7 by 84, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 84

Step 2:
If we divide 79 by 84, we get 0 and a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Grab the next digit (1) from the dividend, add it to 79, then carry on: 791 / 84

Let's proceed to step 3:
84 goes into 791 9 times with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 756 away from 791, we end up with 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 84

Step 4:
When dividing 358 by 84, we get 4 with a remainder of 22.
The next digit of our result is 4. 
Result so far: 94.0
If we subtract 336 from 358, we get 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 84

Going ahead to step 5:
84 goes into 229 2 times with a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 942.0
If we subtract 168 from 229, we get 61.
Grab the next digit (0) from the dividend, add it to 61, then carry on: 610 / 84

Going ahead to step 6:
The number 84 fits into 610 7 times, leaving a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 9427.0
Subtracting 588 from 610 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
If we divide 220 by 84, we get 2 and a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 9427.2
If we subtract 168 from 220, we get 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 8:
520 divided by 84 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 9427.26
If we subtract 504 from 520, we get 16.
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 9:
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: 9427.261
Subtracting 84 from 160 leaves us with 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 10:
When dividing 760 by 84, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 9427.2619
The remainder is 4 after subtracting 756 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
When dividing 40 by 84, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 9427.2619
Deduct 0 from 40 and we're left 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.

Step 12:
If we divide 400 by 84, we get 4 and a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 9427.261904
If we subtract 336 from 400, 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.

On to step 13:
The number 84 fits into 640 7 times, leaving a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 9427.2619047
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 14:
520 divided by 84 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 9427.26190476
Subtract 504 from 520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 9427.26190476 with a balance of 1.6e-08.
