635920 divided by 83 
The aim is to understand the frequency of 83 in 635920.

Let's proceed to step 1:
6 divided by 83 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 83

Advancing to step 2:
If we divide 63 by 83, we get 0 and a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Bring next digit (5) of the dividend behind the 63 and repeat the process: 635 / 83

Advancing to step 3:
635 divided by 83 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 581 away from 635, we end up with 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 83

Step 4:
83 can be fit into 549 6 times, resulting in a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 76.0
Subtract 498 from 549 to get 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 83

Advancing to step 5:
When dividing 512 by 83, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 766.0
If we subtract 498 from 512, we get 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 83

Advancing to step 6:
When dividing 140 by 83, we get 1 with a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 7661.0
Subtracting 83 from 140 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
83 can be fit into 570 6 times, resulting in a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 7661.6
Deduct 498 from 570 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 8:
83 can be fit into 720 8 times, resulting in a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 7661.68
The remainder is 56 after subtracting 664 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
560 divided by 83 is 6 with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 7661.686
Subtract 498 from 560 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
If we divide 620 by 83, we get 7 and a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 7661.6867
Subtracting 581 from 620 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 11:
The number 83 fits into 390 4 times, leaving a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 7661.68674
The remainder is 58 after subtracting 332 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
If we divide 580 by 83, we get 6 and a remainder of 82.
Record the quotient 6 as the next digit in the result. 
Result so far: 7661.686746
The remainder is 82 after subtracting 498 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 13:
83 can be fit into 820 9 times, resulting in a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 7661.6867469
If we take 747 away from 820, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 14:
83 can be fit into 730 8 times, resulting in a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 7661.68674698
Subtract 664 from 730 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 7661.68674698, with a leftover of 6.6e-08.
