83797831 ÷ 873 
The aim is to understand the frequency of 873 in 83797831.

Let's proceed to step 1:
When dividing 8 by 873, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 873

Let's proceed to step 2:
873 goes into 83 0 times with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Include the next digit (7) from the dividend after 83, then repeat: 837 / 873

Moving on to step 3:
837 divided by 873 is 0 with a remainder of 837.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 837 after subtracting 0 from 837.
Bring next digit (9) of the dividend behind the 837 and repeat the process: 8379 / 873

Let's proceed to step 4:
If we divide 8379 by 873, we get 9 and a remainder of 522.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 7857 from 8379 to get 522.
Append the next digit (7) from the dividend to 522 and continue with: 5227 / 873

Advancing to step 5:
If we divide 5227 by 873, we get 5 and a remainder of 862.
Use 5 as the next digit of our solution. 
Result so far: 95.0
If we subtract 4365 from 5227, we get 862.
Bring next digit (8) of the dividend behind the 862 and repeat the process: 8628 / 873

On to step 6:
873 goes into 8628 9 times with a remainder of 771.
Record the quotient 9 as the next digit in the result. 
Result so far: 959.0
Subtract 7857 from 8628 to get 771.
Take the next digit (3) from the dividend and append it to 771, then repeat: 7713 / 873

Moving on to step 7:
7713 divided by 873 is 8 with a remainder of 729.
Use 8 as the next digit of our solution. 
Result so far: 9598.0
Subtract 6984 from 7713 to get 729.
Take the next digit (1) from the dividend and append it to 729, then repeat: 7291 / 873

Advancing to step 8:
The number 873 fits into 7291 8 times, leaving a remainder of 307.
The next digit of our result is 8. 
Result so far: 95988.0
The remainder is 307 after subtracting 6984 from 7291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 9:
873 can be fit into 3070 3 times, resulting in a remainder of 451.
Record the quotient 3 as the next digit in the result. 
Result so far: 95988.3
Subtract 2619 from 3070 to get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Step 10:
When dividing 4510 by 873, we get 5 with a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 95988.35
Subtracting 4365 from 4510 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 11:
873 can be fit into 1450 1 times, resulting in a remainder of 577.
The number 1 becomes the next digit in our result. 
Result so far: 95988.351
If we subtract 873 from 1450, we get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

On to step 12:
If we divide 5770 by 873, we get 6 and a remainder of 532.
Record the quotient 6 as the next digit in the result. 
Result so far: 95988.3516
If we take 5238 away from 5770, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Moving on to step 13:
If we divide 5320 by 873, we get 6 and a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 95988.35166
Subtract 5238 from 5320 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Our division results in 95988.35166 with a remaining 8.2e-05.
