We look at the division of 672506 by 84 
The aim is to understand the frequency of 84 in 672506.

On to step 1:
84 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 84

Advancing to step 2:
84 can be fit into 67 0 times, resulting in a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Take the next digit (2) from the dividend and append it to 67, then repeat: 672 / 84

Step 3:
The number 84 fits into 672 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 0 after subtracting 672 from 672.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 84

Advancing to step 4:
84 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 80.0
If we subtract 0 from 5, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 84

Let's proceed to step 5:
84 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 800.0
If we take 0 away from 50, we end up with 50.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 84

Advancing to step 6:
84 can be fit into 506 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 8006.0
Subtracting 504 from 506 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
The number 84 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8006.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 84, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 8006.02
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
If we divide 320 by 84, we get 3 and a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 8006.023
The remainder is 68 after subtracting 252 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 10:
84 goes into 680 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 8006.0238
Subtract 672 from 680 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
84 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 8006.0238
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
84 goes into 800 9 times with a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 8006.023809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
440 divided by 84 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 8006.0238095
The remainder is 20 after subtracting 420 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 8006.02380952
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 8006.02380952 with a remaining 3.2e-08.
