77518 ÷ 83 
The aim is to understand the frequency of 83 in 77518.

On to step 1:
7 divided by 83 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 83

Moving on to step 2:
77 divided by 83 is 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (5) from the dividend, add it to 77, then carry on: 775 / 83

On to step 3:
83 goes into 775 9 times with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 28 after subtracting 747 from 775.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 83

Moving on to step 4:
If we divide 281 by 83, we get 3 and a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we take 249 away from 281, we end up with 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 83

On to step 5:
83 goes into 328 3 times with a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 933.0
The remainder is 79 after subtracting 249 from 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 6:
The number 83 fits into 790 9 times, leaving a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 933.9
If we take 747 away from 790, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
The number 83 fits into 430 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 933.95
Deduct 415 from 430 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
The number 83 fits into 150 1 times, leaving a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 933.951
The remainder is 67 after subtracting 83 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 9:
670 divided by 83 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 933.9518
If we subtract 664 from 670, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
60 divided by 83 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 933.9518
Deduct 0 from 60 and we're left with 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:
600 divided by 83 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 933.951807
Deduct 581 from 600 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
83 can be fit into 190 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 933.9518072
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.

Going ahead to step 13:
If we divide 240 by 83, we get 2 and a remainder of 74.
The next digit of our result is 2. 
Result so far: 933.95180722
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 933.95180722, with a leftover of 7.4e-08.
