717807 divided by 83 
The aim is to understand the frequency of 83 in 717807.

On to step 1:
The number 83 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 83

On to step 2:
71 divided by 83 is 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Append the next digit (7) from the dividend to 71 and continue with: 717 / 83

Step 3:
The number 83 fits into 717 8 times, leaving a remainder of 53.
The next digit of our result is 8. 
Result so far: 8.0
If we take 664 away from 717, we end up with 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 83

Advancing to step 4:
The number 83 fits into 538 6 times, leaving a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtracting 498 from 538 leaves us with 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 83

Step 5:
83 goes into 400 4 times with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 864.0
Subtract 332 from 400 to get 68.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 83

Going ahead to step 6:
The number 83 fits into 687 8 times, leaving a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 8648.0
Deduct 664 from 687 and we're left 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.

On to step 7:
If we divide 230 by 83, we get 2 and a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 8648.2
If we take 166 away from 230, we end up 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.

Moving on to step 8:
The number 83 fits into 640 7 times, leaving a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 8648.27
Subtracting 581 from 640 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
83 can be fit into 590 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 8648.277
Deduct 581 from 590 and we're left 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.

In conclusion, the division gives 8648.277 with a balance of 0.0009.
