We look at the division of 449644 by 83 
The aim is to understand the frequency of 83 in 449644.

Moving on to step 1:
When dividing 4 by 83, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 83

On to step 2:
83 can be fit into 44 0 times, resulting in a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 83

Going ahead to step 3:
If we divide 449 by 83, we get 5 and a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 415 away from 449, we end up with 34.
Append the next digit (6) from the dividend to 34 and continue with: 346 / 83

Moving on to step 4:
83 goes into 346 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
Subtracting 332 from 346 leaves us with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 83

Going ahead to step 5:
83 can be fit into 144 1 times, resulting in a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 541.0
If we take 83 away from 144, we end up with 61.
Append the next digit (4) from the dividend to 61 and continue with: 614 / 83

Advancing to step 6:
When dividing 614 by 83, we get 7 with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 5417.0
The remainder is 33 after subtracting 581 from 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
If we divide 330 by 83, we get 3 and a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 5417.3
Subtracting 249 from 330 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 8:
83 goes into 810 9 times with a remainder of 63.
The next digit of our result is 9. 
Result so far: 5417.39
The remainder is 63 after subtracting 747 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
The number 83 fits into 630 7 times, leaving a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 5417.397
If we subtract 581 from 630, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 10:
The number 83 fits into 490 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 5417.3975
If we subtract 415 from 490, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 11:
The number 83 fits into 750 9 times, leaving a remainder of 3.
The next digit of our result is 9. 
Result so far: 5417.39759
Subtract 747 from 750 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
83 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 5417.39759
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
83 can be fit into 300 3 times, resulting in a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 5417.3975903
Subtract 249 from 300 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 14:
The number 83 fits into 510 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 5417.39759036
The remainder is 12 after subtracting 498 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 5417.39759036 with a remaining 1.2e-08.
