We look at the division of 304550 by 84 
The aim is to understand the frequency of 84 in 304550.

Moving on to step 1:
If we divide 3 by 84, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 84

Let's proceed to step 2:
If we divide 30 by 84, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 84

Going ahead to step 3:
If we divide 304 by 84, we get 3 and a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 252 from 304 to get 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 84

Step 4:
The number 84 fits into 525 6 times, leaving a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we take 504 away from 525, we end up with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 84

Let's proceed to step 5:
The number 84 fits into 215 2 times, leaving a remainder of 47.
Record the quotient 2 as the next digit in the result. 
Result so far: 362.0
Subtracting 168 from 215 leaves us with 47.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 84

Moving on to step 6:
The number 84 fits into 470 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3625.0
If we subtract 420 from 470, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
500 divided by 84 is 5 with a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 3625.5
Subtracting 420 from 500 leaves us 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.

Moving on to step 8:
When dividing 800 by 84, we get 9 with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 3625.59
Subtracting 756 from 800 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
If we divide 440 by 84, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 3625.595
Subtracting 420 from 440 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.

Advancing to step 10:
When dividing 200 by 84, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 3625.5952
Subtracting 168 from 200 leaves us 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.

Advancing to step 11:
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: 3625.59523
If we take 252 away from 320, we end up with 68.
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 12:
The number 84 fits into 680 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 3625.595238
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.

Going ahead to step 13:
84 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 3625.595238
Subtracting 0 from 80 leaves us 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.

Moving on to step 14:
800 divided by 84 is 9 with a remainder of 44.
The next digit of our result is 9. 
Result so far: 3625.59523809
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 3625.59523809, and the remainder is 4.4e-08.
