We look at the division of 251029 by 83 
The aim is to understand the frequency of 83 in 251029.

On to step 1:
83 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 83

Advancing to step 2:
When dividing 25 by 83, we get 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 83

Moving on to step 3:
If we divide 251 by 83, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 249 from 251 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 83

Step 4:
When dividing 20 by 83, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 83

Let's proceed to step 5:
83 goes into 202 2 times with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 302.0
If we subtract 166 from 202, we get 36.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 83

Advancing to step 6:
If we divide 369 by 83, we get 4 and a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 3024.0
Deduct 332 from 369 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
If we divide 370 by 83, we get 4 and a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 3024.4
Subtracting 332 from 370 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
If we divide 380 by 83, we get 4 and a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 3024.44
Subtracting 332 from 380 leaves us 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 3024.44 with a remainder of 0.048.
