624641 ÷ 83 
The aim is to understand the frequency of 83 in 624641.

Let's proceed to step 1:
83 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 83

Moving on to step 2:
83 can be fit into 62 0 times, resulting in a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 83

Moving on to step 3:
When dividing 624 by 83, we get 7 with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 581 from 624 and we're left with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 83

On to step 4:
When dividing 436 by 83, we get 5 with a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we subtract 415 from 436, we get 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 83

Advancing to step 5:
83 can be fit into 214 2 times, resulting in a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 752.0
Subtracting 166 from 214 leaves us with 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 83

Going ahead to step 6:
When dividing 481 by 83, we get 5 with a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 7525.0
If we take 415 away from 481, we end up 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.

Advancing to step 7:
When dividing 660 by 83, we get 7 with a remainder of 79.
Use 7 as the next digit of our solution. 
Result so far: 7525.7
If we subtract 581 from 660, we 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.

Going ahead to step 8:
83 can be fit into 790 9 times, resulting in a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 7525.79
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.

Let's proceed to step 9:
83 goes into 430 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 7525.795
The remainder is 15 after subtracting 415 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
The number 83 fits into 150 1 times, leaving a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 7525.7951
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.

Let's proceed to step 11:
83 can be fit into 670 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 7525.79518
Subtracting 664 from 670 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
When dividing 60 by 83, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 7525.79518
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.

Going ahead to step 13:
83 can be fit into 600 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 7525.7951807
If we take 581 away from 600, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
83 can be fit into 190 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 7525.79518072
Subtract 166 from 190 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 7525.79518072, with a leftover of 2.4e-08.
