We look at the division of 225108 by 83 
The aim is to understand the frequency of 83 in 225108.

Let's proceed to step 1:
2 divided by 83 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 83

On to step 2:
When dividing 22 by 83, we get 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 83

Advancing to step 3:
225 divided by 83 is 2 with a remainder of 59.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 166 from 225, we get 59.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 83

Step 4:
83 can be fit into 591 7 times, resulting in a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtracting 581 from 591 leaves us with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 83

Going ahead to step 5:
When dividing 100 by 83, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 271.0
Deduct 83 from 100 and we're left with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 83

Step 6:
If we divide 178 by 83, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2712.0
Subtracting 166 from 178 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
If we divide 120 by 83, we get 1 and a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 2712.1
If we subtract 83 from 120, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
370 divided by 83 is 4 with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 2712.14
If we take 332 away from 370, we end up 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.

Advancing to step 9:
If we divide 380 by 83, we get 4 and a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 2712.144
If we take 332 away from 380, we end up 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 outcome is 2712.144, with a leftover of 0.0048.
