Let's divide 979294 by 81
The aim is to understand the frequency of 81 in 979294.

On to step 1:
81 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 81

On to step 2:
81 goes into 97 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 81 away from 97, we end up with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 81

Going ahead to step 3:
81 can be fit into 169 2 times, resulting in a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 7 after subtracting 162 from 169.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 81

On to step 4:
The number 81 fits into 72 0 times, leaving a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Subtract 0 from 72 to get 72.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 81

Advancing to step 5:
729 divided by 81 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 1209.0
Subtract 729 from 729 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 81

Moving on to step 6:
81 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 12090.0
If we take 0 away from 4, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
81 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 12090.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
The number 81 fits into 400 4 times, leaving a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 12090.04
Subtracting 324 from 400 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
81 can be fit into 760 9 times, resulting in a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 12090.049
Subtracting 729 from 760 leaves us 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.

Let's proceed to step 10:
The number 81 fits into 310 3 times, leaving a remainder of 67.
The next digit of our result is 3. 
Result so far: 12090.0493
Subtracting 243 from 310 leaves us 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.

Moving on to step 11:
81 can be fit into 670 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 12090.04938
Deduct 648 from 670 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
81 goes into 220 2 times with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 12090.049382
The remainder is 58 after subtracting 162 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 13:
When dividing 580 by 81, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 12090.0493827
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
If we divide 130 by 81, we get 1 and a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 12090.04938271
Subtract 81 from 130 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 12090.04938271 with a remainder of 4.9e-08.
