We look at the division of 163210 by 83 
The aim is to understand the frequency of 83 in 163210.

On to step 1:
83 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 83

Let's proceed to step 2:
When dividing 16 by 83, we get 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 83

On to step 3:
163 divided by 83 is 1 with a remainder of 80.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 83 away from 163, we end up with 80.
Bring next digit (2) of the dividend behind the 80 and repeat the process: 802 / 83

On to step 4:
802 divided by 83 is 9 with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 747 from 802, we get 55.
Take the next digit (1) from the dividend and append it to 55, then repeat: 551 / 83

Moving on to step 5:
83 goes into 551 6 times with a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 196.0
If we take 498 away from 551, we end up with 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 83

On to step 6:
When dividing 530 by 83, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 1966.0
If we take 498 away from 530, we end up 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.

On to step 7:
The number 83 fits into 320 3 times, leaving a remainder of 71.
The next digit of our result is 3. 
Result so far: 1966.3
If we take 249 away from 320, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 8:
If we divide 710 by 83, we get 8 and a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 1966.38
Deduct 664 from 710 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
460 divided by 83 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1966.385
Subtracting 415 from 460 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
The number 83 fits into 450 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 1966.3855
If we subtract 415 from 450, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 1966.3855 with a remaining 0.00035.
