63399 divided by 83 
The aim is to understand the frequency of 83 in 63399.

Going ahead to step 1:
The number 83 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 83

On to step 2:
When dividing 63 by 83, we get 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Include the next digit (3) from the dividend after 63, then repeat: 633 / 83

On to step 3:
When dividing 633 by 83, we get 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 581 from 633, we get 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 83

Going ahead to step 4:
83 can be fit into 529 6 times, resulting in a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 76.0
If we take 498 away from 529, we end up with 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 83

Step 5:
319 divided by 83 is 3 with a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 763.0
If we take 249 away from 319, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 6:
83 goes into 700 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 763.8
Deduct 664 from 700 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
The number 83 fits into 360 4 times, leaving a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 763.84
Deduct 332 from 360 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
83 can be fit into 280 3 times, resulting in a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 763.843
Deduct 249 from 280 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
83 can be fit into 310 3 times, resulting in a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 763.8433
If we take 249 away from 310, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 763.8433 and a remainder of 0.00061.
