122747 ÷ 81 
The aim is to understand the frequency of 81 in 122747.

Step 1:
81 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 81

Moving on to step 2:
The number 81 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 81

Moving on to step 3:
When dividing 122 by 81, we get 1 with a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 81 from 122 leaves us with 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 81

Advancing to step 4:
81 can be fit into 417 5 times, resulting in a remainder of 12.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 405 from 417 and we're left with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 81

Step 5:
81 can be fit into 124 1 times, resulting in a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 151.0
Subtracting 81 from 124 leaves us with 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 81

Advancing to step 6:
If we divide 437 by 81, we get 5 and a remainder of 32.
Write down 5 as next digit of the result. 
Result so far: 1515.0
If we subtract 405 from 437, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
320 divided by 81 is 3 with a remainder of 77.
The next digit of our result is 3. 
Result so far: 1515.3
Subtract 243 from 320 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 8:
81 can be fit into 770 9 times, resulting in a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 1515.39
If we subtract 729 from 770, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 9:
410 divided by 81 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1515.395
Subtract 405 from 410 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
81 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1515.395
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
500 divided by 81 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 1515.39506
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
140 divided by 81 is 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 1515.395061
If we take 81 away from 140, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 13:
590 divided by 81 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 1515.3950617
If we subtract 567 from 590, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 14:
230 divided by 81 is 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 1515.39506172
The remainder is 68 after subtracting 162 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 1515.39506172 and a remainder of 6.8e-08.
