We look at the division of 671308 by 83 
The aim is to understand the frequency of 83 in 671308.

Step 1:
The number 83 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 83

Going ahead to step 2:
67 divided by 83 is 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Append the next digit (1) from the dividend to 67 and continue with: 671 / 83

Let's proceed to step 3:
The number 83 fits into 671 8 times, leaving a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 664 from 671 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 83

Going ahead to step 4:
83 goes into 73 0 times with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 80.0
The remainder is 73 after subtracting 0 from 73.
Include the next digit (0) from the dividend after 73, then repeat: 730 / 83

Let's proceed to step 5:
If we divide 730 by 83, we get 8 and a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 808.0
The remainder is 66 after subtracting 664 from 730.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 83

Advancing to step 6:
The number 83 fits into 668 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 8088.0
Subtract 664 from 668 to 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.

Moving on to step 7:
When dividing 40 by 83, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8088.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
400 divided by 83 is 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 8088.04
Deduct 332 from 400 and we're left 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.

Moving on to step 9:
When dividing 680 by 83, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 8088.048
If we take 664 away from 680, we end up 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.

Step 10:
If we divide 160 by 83, we get 1 and a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 8088.0481
If we take 83 away from 160, we end up 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.

Moving on to step 11:
When dividing 770 by 83, we get 9 with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 8088.04819
The remainder is 23 after subtracting 747 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 12:
230 divided by 83 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 8088.048192
Deduct 166 from 230 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
When dividing 640 by 83, we get 7 with a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 8088.0481927
The remainder is 59 after subtracting 581 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 14:
The number 83 fits into 590 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 8088.04819277
If we take 581 away from 590, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 8088.04819277 and a remainder of 9e-09.
