282237 ÷ 81 
The aim is to understand the frequency of 81 in 282237.

On to step 1:
The number 81 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 81

On to step 2:
81 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 81

Let's proceed to step 3:
If we divide 282 by 81, we get 3 and a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 243 from 282, we get 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 81

Step 4:
If we divide 392 by 81, we get 4 and a remainder of 68.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 324 from 392, we get 68.
Append the next digit (3) from the dividend to 68 and continue with: 683 / 81

Step 5:
81 goes into 683 8 times with a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 348.0
Subtract 648 from 683 to get 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 81

Let's proceed to step 6:
When dividing 357 by 81, we get 4 with a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 3484.0
If we subtract 324 from 357, we get 33.
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 7:
81 goes into 330 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 3484.4
If we take 324 away from 330, we end up 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.

Moving on to step 8:
60 divided by 81 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 3484.4
Deduct 0 from 60 and we're left 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.

Going ahead to step 9:
81 goes into 600 7 times with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 3484.407
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.

Advancing to step 10:
330 divided by 81 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 3484.4074
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.

Moving on to step 11:
If we divide 60 by 81, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 3484.4074
Deduct 0 from 60 and we're left 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.

Let's proceed to step 12:
81 goes into 600 7 times with a remainder of 33.
The next digit of our result is 7. 
Result so far: 3484.407407
If we take 567 away from 600, we end up 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 13:
81 can be fit into 330 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 3484.4074074
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 14:
81 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 3484.4074074
Subtract 0 from 60 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.

Our division results in 3484.4074074 with a remaining 6e-08.
