Let's divide 263686 by 84
The aim is to understand the frequency of 84 in 263686.

Let's proceed to step 1:
2 divided by 84 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 84

Going ahead to step 2:
84 goes into 26 0 times with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 84

Step 3:
When dividing 263 by 84, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 252 from 263 and we're left with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 84

On to step 4:
The number 84 fits into 116 1 times, leaving a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 32 after subtracting 84 from 116.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 84

Let's proceed to step 5:
84 can be fit into 328 3 times, resulting in a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 313.0
If we subtract 252 from 328, we get 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 84

Advancing to step 6:
84 goes into 766 9 times with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 3139.0
Subtracting 756 from 766 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
If we divide 100 by 84, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 3139.1
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
If we divide 160 by 84, we get 1 and a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 3139.11
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.

The final outcome is 3139.11, with a leftover of 0.076.
