We look at the division of 263669 by 84 
The aim is to understand the frequency of 84 in 263669.

Let's proceed to step 1:
2 divided by 84 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 84

Let's proceed to step 2:
84 goes into 26 0 times with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 84

Moving on to step 3:
263 divided by 84 is 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 11 after subtracting 252 from 263.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 84

On to step 4:
84 goes into 116 1 times with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 84 from 116 leaves us with 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 84

Step 5:
84 can be fit into 326 3 times, resulting in a remainder of 74.
The next digit of our result is 3. 
Result so far: 313.0
If we subtract 252 from 326, we get 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 84

Step 6:
The number 84 fits into 749 8 times, leaving a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 3138.0
Subtracting 672 from 749 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 7:
84 goes into 770 9 times with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 3138.9
The remainder is 14 after subtracting 756 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
84 goes into 140 1 times with a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 3138.91
Subtract 84 from 140 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
When dividing 560 by 84, we get 6 with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 3138.916
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
560 divided by 84 is 6 with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 3138.9166
If we take 504 away from 560, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 3138.9166 with a balance of 0.00056.
