408395 ÷ 83 
The aim is to understand the frequency of 83 in 408395.

Moving on to step 1:
When dividing 4 by 83, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 83

On to step 2:
83 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 83

Step 3:
When dividing 408 by 83, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 76 after subtracting 332 from 408.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 83

Advancing to step 4:
If we divide 763 by 83, we get 9 and a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 16 after subtracting 747 from 763.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 83

Going ahead to step 5:
83 goes into 169 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 492.0
If we take 166 away from 169, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 83

Advancing to step 6:
83 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 4920.0
Deduct 0 from 35 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
If we divide 350 by 83, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4920.4
Subtracting 332 from 350 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
83 can be fit into 180 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 4920.42
Subtracting 166 from 180 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
140 divided by 83 is 1 with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 4920.421
The remainder is 57 after subtracting 83 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 10:
The number 83 fits into 570 6 times, leaving a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 4920.4216
Subtracting 498 from 570 leaves us 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.

Step 11:
720 divided by 83 is 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 4920.42168
Deduct 664 from 720 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
When dividing 560 by 83, we get 6 with a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 4920.421686
If we take 498 away from 560, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
The number 83 fits into 620 7 times, leaving a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 4920.4216867
The remainder is 39 after subtracting 581 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 14:
The number 83 fits into 390 4 times, leaving a remainder of 58.
The next digit of our result is 4. 
Result so far: 4920.42168674
Subtracting 332 from 390 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 4920.42168674, with a leftover of 5.8e-08.
