We're dividing 628460 by 83 
The aim is to understand the frequency of 83 in 628460.

Moving on to step 1:
If we divide 6 by 83, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 83

Going ahead to step 2:
When dividing 62 by 83, we get 0 with a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Take the next digit (8) from the dividend and append it to 62, then repeat: 628 / 83

On to step 3:
83 can be fit into 628 7 times, resulting in a remainder of 47.
The next digit of our result is 7. 
Result so far: 7.0
If we take 581 away from 628, we end up with 47.
Append the next digit (4) from the dividend to 47 and continue with: 474 / 83

Going ahead to step 4:
83 can be fit into 474 5 times, resulting in a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
The remainder is 59 after subtracting 415 from 474.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 83

Step 5:
596 divided by 83 is 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 757.0
If we take 581 away from 596, we end up with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 83

Moving on to step 6:
83 can be fit into 150 1 times, resulting in a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 7571.0
The remainder is 67 after subtracting 83 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 7:
83 can be fit into 670 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 7571.8
The remainder is 6 after subtracting 664 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 83 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 7571.8
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
600 divided by 83 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 7571.807
The remainder is 19 after subtracting 581 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
190 divided by 83 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 7571.8072
Subtracting 166 from 190 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.

Let's proceed to step 11:
83 can be fit into 240 2 times, resulting in a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 7571.80722
Subtract 166 from 240 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final outcome is 7571.80722, with a leftover of 7.4e-05.
