We're dividing 6487 by 83 
The aim is to understand the frequency of 83 in 6487.

Advancing to step 1:
When dividing 6 by 83, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 83

Step 2:
83 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 83

Let's proceed to step 3:
If we divide 648 by 83, we get 7 and a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 581 from 648, we get 67.
Include the next digit (7) from the dividend after 67, then repeat: 677 / 83

Let's proceed to step 4:
83 can be fit into 677 8 times, resulting in a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
If we subtract 664 from 677, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 5:
If we divide 130 by 83, we get 1 and a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 78.1
If we subtract 83 from 130, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 6:
83 goes into 470 5 times with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 78.15
If we subtract 415 from 470, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 7:
When dividing 550 by 83, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 78.156
The remainder is 52 after subtracting 498 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 8:
83 can be fit into 520 6 times, resulting in a remainder of 22.
The next digit of our result is 6. 
Result so far: 78.1566
Deduct 498 from 520 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 78.1566 with a remaining 0.00022.
