We look at the division of 419823 by 83 
The aim is to understand the frequency of 83 in 419823.

Let's proceed to step 1:
83 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 83

Advancing to step 2:
If we divide 41 by 83, we get 0 and a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 83

Going ahead to step 3:
The number 83 fits into 419 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 415 from 419, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 83

On to step 4:
83 goes into 48 0 times with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we subtract 0 from 48, we get 48.
Grab the next digit (2) from the dividend, add it to 48, then carry on: 482 / 83

Moving on to step 5:
482 divided by 83 is 5 with a remainder of 67.
Use 5 as the next digit of our solution. 
Result so far: 505.0
Deduct 415 from 482 and we're left with 67.
Bring next digit (3) of the dividend behind the 67 and repeat the process: 673 / 83

Advancing to step 6:
The number 83 fits into 673 8 times, leaving a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 5058.0
The remainder is 9 after subtracting 664 from 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
90 divided by 83 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 5058.1
If we take 83 away from 90, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
83 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 5058.1
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
83 goes into 700 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 5058.108
If we take 664 away from 700, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
83 goes into 360 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 5058.1084
Subtracting 332 from 360 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
If we divide 280 by 83, we get 3 and a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 5058.10843
The remainder is 31 after subtracting 249 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 12:
If we divide 310 by 83, we get 3 and a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 5058.108433
If we take 249 away from 310, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 5058.108433 with a remaining 6.1e-06.
