We're dividing 680847 by 84 
The aim is to understand the frequency of 84 in 680847.

Moving on to step 1:
6 divided by 84 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 84

Moving on to step 2:
84 goes into 68 0 times with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Append the next digit (0) from the dividend to 68 and continue with: 680 / 84

Let's proceed to step 3:
680 divided by 84 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 672 from 680, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 84

Advancing to step 4:
If we divide 88 by 84, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 81.0
Deduct 84 from 88 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 84

Let's proceed to step 5:
When dividing 44 by 84, we get 0 with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 810.0
Subtract 0 from 44 to get 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 84

Going ahead to step 6:
84 goes into 447 5 times with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 8105.0
Subtracting 420 from 447 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
When dividing 270 by 84, we get 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 8105.3
Subtract 252 from 270 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
84 can be fit into 180 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 8105.32
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.

On to step 9:
84 can be fit into 120 1 times, resulting in a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 8105.321
Subtract 84 from 120 to 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.

Advancing to step 10:
The number 84 fits into 360 4 times, leaving a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 8105.3214
Subtracting 336 from 360 leaves us 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.

Going ahead to step 11:
84 can be fit into 240 2 times, resulting in a remainder of 72.
The next digit of our result is 2. 
Result so far: 8105.32142
If we subtract 168 from 240, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
84 goes into 720 8 times with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 8105.321428
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.

Advancing to step 13:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 8105.3214285
Subtracting 420 from 480 leaves us 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.

Moving on to step 14:
When dividing 600 by 84, we get 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 8105.32142857
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.

The final outcome is 8105.32142857, with a leftover of 1.2e-08.
