We're dividing 297006 by 81 
The aim is to understand the frequency of 81 in 297006.

On to step 1:
2 divided by 81 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 81

Moving on to step 2:
If we divide 29 by 81, we get 0 and a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 81

On to step 3:
81 goes into 297 3 times with a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 243 from 297 to get 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 81

Going ahead to step 4:
If we divide 540 by 81, we get 6 and a remainder of 54.
The next digit of our result is 6. 
Result so far: 36.0
If we subtract 486 from 540, we get 54.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 81

Let's proceed to step 5:
When dividing 540 by 81, we get 6 with a remainder of 54.
The next digit of our result is 6. 
Result so far: 366.0
The remainder is 54 after subtracting 486 from 540.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 81

Advancing to step 6:
546 divided by 81 is 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 3666.0
Subtract 486 from 546 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
When dividing 600 by 81, we get 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 3666.7
Deduct 567 from 600 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 8:
If we divide 330 by 81, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 3666.74
Subtracting 324 from 330 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 81, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 3666.74
If we subtract 0 from 60, we get 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 10:
When dividing 600 by 81, we get 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 3666.7407
The remainder is 33 after subtracting 567 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
81 goes into 330 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 3666.74074
Subtract 324 from 330 to 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.

On to step 12:
81 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 3666.74074
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
81 can be fit into 600 7 times, resulting in a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 3666.7407407
The remainder is 33 after subtracting 567 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 14:
When dividing 330 by 81, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 3666.74074074
If we subtract 324 from 330, 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.

The final outcome is 3666.74074074, with a leftover of 6e-09.
