We look at the division of 247839 by 83 
The aim is to understand the frequency of 83 in 247839.

Step 1:
The number 83 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 83

Let's proceed to step 2:
The number 83 fits into 24 0 times, leaving a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 83

Let's proceed to step 3:
The number 83 fits into 247 2 times, leaving a remainder of 81.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 81 after subtracting 166 from 247.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 83

Going ahead to step 4:
83 goes into 818 9 times with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 747 away from 818, we end up with 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 83

Going ahead to step 5:
If we divide 713 by 83, we get 8 and a remainder of 49.
The next digit of our result is 8. 
Result so far: 298.0
If we subtract 664 from 713, we get 49.
Grab the next digit (9) from the dividend, add it to 49, then carry on: 499 / 83

On to step 6:
If we divide 499 by 83, we get 6 and a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 2986.0
The remainder is 1 after subtracting 498 from 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 83, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2986.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
83 can be fit into 100 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 2986.01
If we subtract 83 from 100, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
170 divided by 83 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2986.012
If we subtract 166 from 170, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
83 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2986.012
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
If we divide 400 by 83, we get 4 and a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 2986.01204
If we take 332 away from 400, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 12:
The number 83 fits into 680 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 2986.012048
Deduct 664 from 680 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
The number 83 fits into 160 1 times, leaving a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 2986.0120481
Subtracting 83 from 160 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 14:
When dividing 770 by 83, we get 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 2986.01204819
If we take 747 away from 770, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 2986.01204819, with a leftover of 2.3e-08.
