Let's divide 312283 by 81
The aim is to understand the frequency of 81 in 312283.

Let's proceed to step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 81

Step 2:
31 divided by 81 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 81

On to step 3:
The number 81 fits into 312 3 times, leaving a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 69 after subtracting 243 from 312.
Append the next digit (2) from the dividend to 69 and continue with: 692 / 81

Step 4:
81 goes into 692 8 times with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 648 from 692, we get 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 81

Advancing to step 5:
The number 81 fits into 448 5 times, leaving a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 385.0
If we subtract 405 from 448, we get 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 81

Advancing to step 6:
When dividing 433 by 81, we get 5 with a remainder of 28.
The next digit of our result is 5. 
Result so far: 3855.0
Subtract 405 from 433 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
81 goes into 280 3 times with a remainder of 37.
The next digit of our result is 3. 
Result so far: 3855.3
Subtracting 243 from 280 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 8:
The number 81 fits into 370 4 times, leaving a remainder of 46.
The next digit of our result is 4. 
Result so far: 3855.34
Subtracting 324 from 370 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
When dividing 460 by 81, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 3855.345
The remainder is 55 after subtracting 405 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
The number 81 fits into 550 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 3855.3456
If we subtract 486 from 550, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
640 divided by 81 is 7 with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 3855.34567
Subtract 567 from 640 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 12:
730 divided by 81 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 3855.345679
Subtracting 729 from 730 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
81 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 3855.345679
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
100 divided by 81 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 3855.34567901
If we subtract 81 from 100, 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.

The final result is 3855.34567901 with a remainder of 1.9e-08.
