752334 divided by 81 
The aim is to understand the frequency of 81 in 752334.

Let's proceed to step 1:
When dividing 7 by 81, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 81

Advancing to step 2:
If we divide 75 by 81, we get 0 and a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Bring next digit (2) of the dividend behind the 75 and repeat the process: 752 / 81

Advancing to step 3:
752 divided by 81 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 729 from 752 and we're left with 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 81

Going ahead to step 4:
81 can be fit into 233 2 times, resulting in a remainder of 71.
Put 2 as the next digit of the answer. 
Result so far: 92.0
The remainder is 71 after subtracting 162 from 233.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 81

On to step 5:
If we divide 713 by 81, we get 8 and a remainder of 65.
Write down 8 as next digit of the result. 
Result so far: 928.0
If we take 648 away from 713, we end up with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 81

Moving on to step 6:
If we divide 654 by 81, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 9288.0
Subtract 648 from 654 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 7:
81 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 9288.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
81 goes into 600 7 times with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 9288.07
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 9:
330 divided by 81 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 9288.074
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.

Moving on to step 10:
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: 9288.074
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.

Moving on to step 11:
600 divided by 81 is 7 with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 9288.07407
Subtracting 567 from 600 leaves us 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.

Let's proceed to step 12:
330 divided by 81 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 9288.074074
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 13:
When dividing 60 by 81, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 9288.074074
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.

Moving on to step 14:
81 can be fit into 600 7 times, resulting in a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 9288.07407407
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.

The quotient of the division is 9288.07407407, and the remainder is 3.3e-08.
