We look at the division of 263802 by 84 
The aim is to understand the frequency of 84 in 263802.

Moving on to step 1:
When dividing 2 by 84, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 84

Let's proceed to step 2:
If we divide 26 by 84, we get 0 and a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 84

On to step 3:
84 can be fit into 263 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 252 from 263 to get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 84

Going ahead to step 4:
84 goes into 118 1 times with a remainder of 34.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 34 after subtracting 84 from 118.
Append the next digit (0) from the dividend to 34 and continue with: 340 / 84

Let's proceed to step 5:
340 divided by 84 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 314.0
If we subtract 336 from 340, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 84

Going ahead to step 6:
The number 84 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 3140.0
If we subtract 0 from 42, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
If we divide 420 by 84, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3140.5
Deduct 420 from 420 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
84 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3140.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 84 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3140.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 3140.5 and a remainder of 0.0.
