812847 ÷ 83 
The aim is to understand the frequency of 83 in 812847.

Step 1:
83 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 83

Going ahead to step 2:
81 divided by 83 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 83

Advancing to step 3:
83 goes into 812 9 times with a remainder of 65.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 747 from 812 leaves us with 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 83

Let's proceed to step 4:
83 can be fit into 658 7 times, resulting in a remainder of 77.
The next digit of our result is 7. 
Result so far: 97.0
If we subtract 581 from 658, we get 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 83

Moving on to step 5:
83 goes into 774 9 times with a remainder of 27.
The next digit of our result is 9. 
Result so far: 979.0
Subtract 747 from 774 to get 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 83

Let's proceed to step 6:
277 divided by 83 is 3 with a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 9793.0
The remainder is 28 after subtracting 249 from 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
If we divide 280 by 83, we get 3 and a remainder of 31.
The next digit of our result is 3. 
Result so far: 9793.3
If we take 249 away from 280, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 8:
83 can be fit into 310 3 times, resulting in a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 9793.33
Subtracting 249 from 310 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 9793.33 and a remainder of 0.061.
