300716 ÷ 81 
The aim is to understand the frequency of 81 in 300716.

On to step 1:
81 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 81

Let's proceed to step 2:
30 divided by 81 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 81

Step 3:
300 divided by 81 is 3 with a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 243 away from 300, we end up with 57.
Fetch the next digit (7) from the dividend, attach it to 57 and continue: 577 / 81

Let's proceed to step 4:
81 can be fit into 577 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtracting 567 from 577 leaves us with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 81

Step 5:
101 divided by 81 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 371.0
If we take 81 away from 101, we end up with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 81

Going ahead to step 6:
When dividing 206 by 81, we get 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 3712.0
Subtract 162 from 206 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
81 goes into 440 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3712.5
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
If we divide 350 by 81, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 3712.54
If we take 324 away from 350, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
When dividing 260 by 81, we get 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3712.543
If we take 243 away from 260, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
170 divided by 81 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 3712.5432
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
When dividing 80 by 81, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 3712.5432
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
If we divide 800 by 81, we get 9 and a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 3712.543209
If we take 729 away from 800, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 13:
81 goes into 710 8 times with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 3712.5432098
Subtracting 648 from 710 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 14:
620 divided by 81 is 7 with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 3712.54320987
If we take 567 away from 620, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The quotient of the division is 3712.54320987, and the remainder is 5.3e-08.
