We look at the division of 359818 by 83 
The aim is to understand the frequency of 83 in 359818.

Let's proceed to step 1:
3 divided by 83 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 83

Moving on to step 2:
The number 83 fits into 35 0 times, leaving a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 83

Advancing to step 3:
If we divide 359 by 83, we get 4 and a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 332 from 359 to get 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 83

Advancing to step 4:
If we divide 278 by 83, we get 3 and a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 249 from 278 and we're left with 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 83

On to step 5:
When dividing 291 by 83, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 433.0
Subtracting 249 from 291 leaves us with 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 83

Moving on to step 6:
83 can be fit into 428 5 times, resulting in a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 4335.0
If we take 415 away from 428, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
83 can be fit into 130 1 times, resulting in a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 4335.1
The remainder is 47 after subtracting 83 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 8:
If we divide 470 by 83, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 4335.15
Deduct 415 from 470 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
When dividing 550 by 83, we get 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 4335.156
Deduct 498 from 550 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
If we divide 520 by 83, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 4335.1566
If we take 498 away from 520, we end up 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 final outcome is 4335.1566, with a leftover of 0.00022.
