We divide 664605 by 83
The aim is to understand the frequency of 83 in 664605.

Let's proceed to step 1:
If we divide 6 by 83, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 83

Moving on to step 2:
If we divide 66 by 83, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 83

Let's proceed to step 3:
83 can be fit into 664 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 664 away from 664, we end up with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 83

Step 4:
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: 80.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 83

Let's proceed to step 5:
60 divided by 83 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 800.0
If we take 0 away from 60, we end up with 60.
Fetch the next digit (5) from the dividend, attach it to 60 and continue: 605 / 83

Advancing to step 6:
If we divide 605 by 83, we get 7 and a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 8007.0
Subtracting 581 from 605 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
When dividing 240 by 83, we get 2 with a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 8007.2
The remainder is 74 after subtracting 166 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 8:
When dividing 740 by 83, we get 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 8007.28
The remainder is 76 after subtracting 664 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
The number 83 fits into 760 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 8007.289
The remainder is 13 after subtracting 747 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
83 can be fit into 130 1 times, resulting in a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 8007.2891
Deduct 83 from 130 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 11:
If we divide 470 by 83, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 8007.28915
Subtract 415 from 470 to 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.

On to step 12:
550 divided by 83 is 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 8007.289156
If we take 498 away from 550, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
520 divided by 83 is 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 8007.2891566
The remainder is 22 after subtracting 498 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 8007.2891566, with a leftover of 2.2e-07.
