We look at the division of 154850 by 83 
The aim is to understand the frequency of 83 in 154850.

Step 1:
If we divide 1 by 83, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 83

Step 2:
The number 83 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 83

Let's proceed to step 3:
The number 83 fits into 154 1 times, leaving a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 83 from 154 and we're left with 71.
Bring next digit (8) of the dividend behind the 71 and repeat the process: 718 / 83

Step 4:
The number 83 fits into 718 8 times, leaving a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 664 from 718 leaves us with 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 83

Step 5:
The number 83 fits into 545 6 times, leaving a remainder of 47.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
Subtracting 498 from 545 leaves us with 47.
Append the next digit (0) from the dividend to 47 and continue with: 470 / 83

Advancing to step 6:
470 divided by 83 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 1865.0
The remainder is 55 after subtracting 415 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 7:
83 can be fit into 550 6 times, resulting in a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 1865.6
Subtract 498 from 550 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
520 divided by 83 is 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 1865.66
Deduct 498 from 520 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 1865.66, and the remainder is 0.022.
