We're dividing 33578 by 83 
The aim is to understand the frequency of 83 in 33578.

Step 1:
If we divide 3 by 83, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 83

Advancing to step 2:
83 goes into 33 0 times with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 83

Going ahead to step 3:
83 can be fit into 335 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 332 from 335 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 83

Advancing to step 4:
83 can be fit into 37 0 times, resulting in a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we take 0 away from 37, we end up with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 83

Step 5:
378 divided by 83 is 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 404.0
If we take 332 away from 378, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 6:
When dividing 460 by 83, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 404.5
If we take 415 away from 460, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
If we divide 450 by 83, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 404.55
Deduct 415 from 450 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 404.55, with a leftover of 0.035.
