We look at the division of 259279 by 83 
The aim is to understand the frequency of 83 in 259279.

Advancing to step 1:
If we divide 2 by 83, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 83

Step 2:
83 can be fit into 25 0 times, resulting in a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 83

On to step 3:
83 can be fit into 259 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 249 from 259 leaves us with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 83

Step 4:
When dividing 102 by 83, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
The remainder is 19 after subtracting 83 from 102.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 83

Moving on to step 5:
83 can be fit into 197 2 times, resulting in a remainder of 31.
Write down 2 as next digit of the result. 
Result so far: 312.0
If we take 166 away from 197, we end up with 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 83

Advancing to step 6:
83 goes into 319 3 times with a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 3123.0
Subtracting 249 from 319 leaves us 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.

Step 7:
700 divided by 83 is 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 3123.8
If we take 664 away from 700, we end up 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.

Let's proceed to step 8:
If we divide 360 by 83, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 3123.84
The remainder is 28 after subtracting 332 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
83 goes into 280 3 times with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 3123.843
Subtracting 249 from 280 leaves us 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.

Step 10:
When dividing 310 by 83, we get 3 with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 3123.8433
If we subtract 249 from 310, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final result is 3123.8433 with a remainder of 0.00061.
