We look at the division of 374323 by 84 
The aim is to understand the frequency of 84 in 374323.

Step 1:
The number 84 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 84

On to step 2:
37 divided by 84 is 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 84

On to step 3:
374 divided by 84 is 4 with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 336 from 374 and we're left with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 84

Moving on to step 4:
383 divided by 84 is 4 with a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Deduct 336 from 383 and we're left with 47.
Include the next digit (2) from the dividend after 47, then repeat: 472 / 84

Advancing to step 5:
472 divided by 84 is 5 with a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 445.0
Deduct 420 from 472 and we're left with 52.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 84

On to step 6:
When dividing 523 by 84, we get 6 with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 4456.0
Subtract 504 from 523 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
The number 84 fits into 190 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 4456.2
The remainder is 22 after subtracting 168 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
If we divide 220 by 84, we get 2 and a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 4456.22
If we subtract 168 from 220, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 4456.22, with a leftover of 0.052.
