We're dividing 433487 by 84 
The aim is to understand the frequency of 84 in 433487.

Step 1:
4 divided by 84 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 84

Moving on to step 2:
The number 84 fits into 43 0 times, leaving a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Grab the next digit (3) from the dividend, add it to 43, then carry on: 433 / 84

Advancing to step 3:
433 divided by 84 is 5 with a remainder of 13.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 420 from 433 to get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 84

Step 4:
If we divide 134 by 84, we get 1 and a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 51.0
The remainder is 50 after subtracting 84 from 134.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 84

On to step 5:
The number 84 fits into 508 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 516.0
If we subtract 504 from 508, we get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 84

Let's proceed to step 6:
If we divide 47 by 84, we get 0 and a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 5160.0
The remainder is 47 after subtracting 0 from 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
When dividing 470 by 84, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5160.5
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.

Let's proceed to step 8:
84 can be fit into 500 5 times, resulting in a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 5160.55
If we take 420 away from 500, we end up 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.

The quotient of the division is 5160.55, and the remainder is 0.08.
