We're dividing 83370 by 84 
The aim is to understand the frequency of 84 in 83370.

On to step 1:
84 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 84

Moving on to step 2:
The number 84 fits into 83 0 times, leaving a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Include the next digit (3) from the dividend after 83, then repeat: 833 / 84

Moving on to step 3:
833 divided by 84 is 9 with a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 77 after subtracting 756 from 833.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 84

Let's proceed to step 4:
The number 84 fits into 777 9 times, leaving a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtracting 756 from 777 leaves us with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 84

Advancing to step 5:
84 can be fit into 210 2 times, resulting in a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 992.0
Subtracting 168 from 210 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 6:
When dividing 420 by 84, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 992.5
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.

On to step 7:
84 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 992.5
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.

Moving on to step 8:
When dividing 0 by 84, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 992.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 992.5 with a remainder of 0.0.
