We're dividing 297870 by 83 
The aim is to understand the frequency of 83 in 297870.

On to step 1:
2 divided by 83 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 83

Moving on to step 2:
83 goes into 29 0 times with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Append the next digit (7) from the dividend to 29 and continue with: 297 / 83

Moving on to step 3:
83 goes into 297 3 times with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 249 away from 297, we end up with 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 83

Moving on to step 4:
488 divided by 83 is 5 with a remainder of 73.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtract 415 from 488 to get 73.
Fetch the next digit (7) from the dividend, attach it to 73 and continue: 737 / 83

Advancing to step 5:
83 goes into 737 8 times with a remainder of 73.
Use 8 as the next digit of our solution. 
Result so far: 358.0
Subtracting 664 from 737 leaves us with 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 83

Moving on to step 6:
83 can be fit into 730 8 times, resulting in a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 3588.0
If we take 664 away from 730, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 7:
If we divide 660 by 83, we get 7 and a remainder of 79.
The next digit of our result is 7. 
Result so far: 3588.7
Subtract 581 from 660 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 8:
83 can be fit into 790 9 times, resulting in a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 3588.79
The remainder is 43 after subtracting 747 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
430 divided by 83 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3588.795
Subtract 415 from 430 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
When dividing 150 by 83, we get 1 with a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 3588.7951
If we take 83 away from 150, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 11:
The number 83 fits into 670 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 3588.79518
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.

Going ahead to step 12:
When dividing 60 by 83, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 3588.79518
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
600 divided by 83 is 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 3588.7951807
If we subtract 581 from 600, we get 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 14:
If we divide 190 by 83, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 3588.79518072
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.

Our division results in 3588.79518072 with a remaining 2.4e-08.
