811209 divided by 83 
The aim is to understand the frequency of 83 in 811209.

On to step 1:
83 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 83

Going ahead to step 2:
81 divided by 83 is 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 83

Let's proceed to step 3:
When dividing 811 by 83, we get 9 with a remainder of 64.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 747 from 811, we get 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 83

Step 4:
83 can be fit into 642 7 times, resulting in a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we subtract 581 from 642, we get 61.
Include the next digit (0) from the dividend after 61, then repeat: 610 / 83

Going ahead to step 5:
83 can be fit into 610 7 times, resulting in a remainder of 29.
The next digit of our result is 7. 
Result so far: 977.0
If we subtract 581 from 610, we get 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 83

On to step 6:
83 can be fit into 299 3 times, resulting in a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 9773.0
The remainder is 50 after subtracting 249 from 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
The number 83 fits into 500 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 9773.6
Subtracting 498 from 500 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
When dividing 20 by 83, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9773.6
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
83 can be fit into 200 2 times, resulting in a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 9773.602
Deduct 166 from 200 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
If we divide 340 by 83, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 9773.6024
If we subtract 332 from 340, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
When dividing 80 by 83, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 9773.6024
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
When dividing 800 by 83, we get 9 with a remainder of 53.
The next digit of our result is 9. 
Result so far: 9773.602409
If we take 747 away from 800, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 13:
83 can be fit into 530 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 9773.6024096
Subtracting 498 from 530 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
The number 83 fits into 320 3 times, leaving a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 9773.60240963
Subtract 249 from 320 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

In conclusion, the division gives 9773.60240963 with a balance of 7.1e-08.
