We're dividing 84321166 by 83 
The aim is to understand the frequency of 83 in 84321166.

Moving on to step 1:
When dividing 8 by 83, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 83

Let's proceed to step 2:
When dividing 84 by 83, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 83 from 84 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 83

Step 3:
If we divide 13 by 83, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 83

Advancing to step 4:
The number 83 fits into 132 1 times, leaving a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtracting 83 from 132 leaves us with 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 83

Let's proceed to step 5:
The number 83 fits into 491 5 times, leaving a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 1015.0
If we subtract 415 from 491, we get 76.
Take the next digit (1) from the dividend and append it to 76, then repeat: 761 / 83

Moving on to step 6:
83 goes into 761 9 times with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 10159.0
The remainder is 14 after subtracting 747 from 761.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 83

Let's proceed to step 7:
If we divide 146 by 83, we get 1 and a remainder of 63.
The next digit of our result is 1. 
Result so far: 101591.0
If we take 83 away from 146, we end up with 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 83

Going ahead to step 8:
The number 83 fits into 636 7 times, leaving a remainder of 55.
The next digit of our result is 7. 
Result so far: 1015917.0
Subtracting 581 from 636 leaves us 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.

Let's proceed to step 9:
If we divide 550 by 83, we get 6 and a remainder of 52.
The next digit of our result is 6. 
Result so far: 1015917.6
If we take 498 away from 550, we end up 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.

Let's proceed to step 10:
When dividing 520 by 83, we get 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 1015917.66
Subtracting 498 from 520 leaves us 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 1015917.66, with a leftover of 0.022.
