We're dividing 865982 by 83 
The aim is to understand the frequency of 83 in 865982.

Moving on to step 1:
If we divide 8 by 83, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 83

Step 2:
The number 83 fits into 86 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 83 from 86, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 83

Advancing to step 3:
35 divided by 83 is 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 83

Moving on to step 4:
The number 83 fits into 359 4 times, leaving a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we subtract 332 from 359, we get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 83

Let's proceed to step 5:
83 goes into 278 3 times with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 1043.0
Deduct 249 from 278 and we're left with 29.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 83

Advancing to step 6:
83 goes into 292 3 times with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 10433.0
The remainder is 43 after subtracting 249 from 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
The number 83 fits into 430 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 10433.5
Subtract 415 from 430 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
83 goes into 150 1 times with a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 10433.51
Subtracting 83 from 150 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
The number 83 fits into 670 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 10433.518
Deduct 664 from 670 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
60 divided by 83 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 10433.518
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
83 goes into 600 7 times with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 10433.51807
If we subtract 581 from 600, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
83 can be fit into 190 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 10433.518072
If we take 166 away from 190, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
83 goes into 240 2 times with a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 10433.5180722
If we take 166 away from 240, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final outcome is 10433.5180722, with a leftover of 7.4e-07.
