539209 ÷ 83 
The aim is to understand the frequency of 83 in 539209.

Step 1:
When dividing 5 by 83, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 83

On to step 2:
If we divide 53 by 83, we get 0 and a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 83

Advancing to step 3:
83 goes into 539 6 times with a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 498 from 539 and we're left with 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 83

On to step 4:
412 divided by 83 is 4 with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Deduct 332 from 412 and we're left with 80.
Grab the next digit (0) from the dividend, add it to 80, then carry on: 800 / 83

Going ahead to step 5:
800 divided by 83 is 9 with a remainder of 53.
The next digit of our result is 9. 
Result so far: 649.0
Subtracting 747 from 800 leaves us with 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 83

Moving on to step 6:
83 goes into 539 6 times with a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 6496.0
Subtract 498 from 539 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
If we divide 410 by 83, we get 4 and a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 6496.4
Subtracting 332 from 410 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 8:
780 divided by 83 is 9 with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 6496.49
Subtract 747 from 780 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
83 goes into 330 3 times with a remainder of 81.
The next digit of our result is 3. 
Result so far: 6496.493
If we take 249 away from 330, we end up 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.

Moving on to step 10:
810 divided by 83 is 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 6496.4939
If we take 747 away from 810, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 11:
83 can be fit into 630 7 times, resulting in a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 6496.49397
Subtract 581 from 630 to 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.

Going ahead to step 12:
If we divide 490 by 83, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 6496.493975
If we take 415 away from 490, we end up with 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 13:
83 can be fit into 750 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 6496.4939759
If we take 747 away from 750, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 14:
83 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 6496.4939759
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 6496.4939759, with a leftover of 3e-08.
