We divide 626400 by 83
The aim is to understand the frequency of 83 in 626400.

Going ahead to step 1:
83 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 83

Going ahead to step 2:
62 divided by 83 is 0 with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Include the next digit (6) from the dividend after 62, then repeat: 626 / 83

Let's proceed to step 3:
When dividing 626 by 83, we get 7 with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 45 after subtracting 581 from 626.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 83

Advancing to step 4:
454 divided by 83 is 5 with a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtracting 415 from 454 leaves us with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 83

On to step 5:
The number 83 fits into 390 4 times, leaving a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 754.0
If we subtract 332 from 390, we get 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 83

On to step 6:
83 goes into 580 6 times with a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 7546.0
Subtract 498 from 580 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 7:
820 divided by 83 is 9 with a remainder of 73.
Use 9 as the next digit of our solution. 
Result so far: 7546.9
Subtract 747 from 820 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 8:
730 divided by 83 is 8 with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 7546.98
Subtracting 664 from 730 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
When dividing 660 by 83, we get 7 with a remainder of 79.
Put 7 as the next digit of the answer. 
Result so far: 7546.987
Subtract 581 from 660 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 10:
If we divide 790 by 83, we get 9 and a remainder of 43.
The next digit of our result is 9. 
Result so far: 7546.9879
The remainder is 43 after subtracting 747 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 11:
If we divide 430 by 83, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 7546.98795
If we take 415 away from 430, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
83 can be fit into 150 1 times, resulting in a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 7546.987951
Subtracting 83 from 150 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 13:
The number 83 fits into 670 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 7546.9879518
If we subtract 664 from 670, we get 6.
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 14:
The number 83 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 7546.9879518
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 7546.9879518 with a remainder of 6e-08.
