We look at the division of 626597 by 83 
The aim is to understand the frequency of 83 in 626597.

Let's proceed to step 1:
The number 83 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 83

On to step 2:
83 goes into 62 0 times with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Take the next digit (6) from the dividend and append it to 62, then repeat: 626 / 83

Advancing to step 3:
83 goes into 626 7 times with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 581 from 626 leaves us with 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 83

Advancing to step 4:
When dividing 455 by 83, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we subtract 415 from 455, we get 40.
Bring next digit (9) of the dividend behind the 40 and repeat the process: 409 / 83

Advancing to step 5:
83 goes into 409 4 times with a remainder of 77.
Write down 4 as next digit of the result. 
Result so far: 754.0
Subtract 332 from 409 to get 77.
Take the next digit (7) from the dividend and append it to 77, then repeat: 777 / 83

Going ahead to step 6:
83 can be fit into 777 9 times, resulting in a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 7549.0
Subtract 747 from 777 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
If we divide 300 by 83, we get 3 and a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 7549.3
The remainder is 51 after subtracting 249 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 8:
If we divide 510 by 83, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 7549.36
If we subtract 498 from 510, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
The number 83 fits into 120 1 times, leaving a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 7549.361
Subtract 83 from 120 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 10:
When dividing 370 by 83, we get 4 with a remainder of 38.
The next digit of our result is 4. 
Result so far: 7549.3614
Subtract 332 from 370 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
83 can be fit into 380 4 times, resulting in a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 7549.36144
If we take 332 away from 380, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 7549.36144 with a remainder of 4.8e-05.
