We look at the division of 53276 by 81 
The aim is to understand the frequency of 81 in 53276.

Moving on to step 1:
If we divide 5 by 81, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 81

Let's proceed to step 2:
53 divided by 81 is 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 81

On to step 3:
When dividing 532 by 81, we get 6 with a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 46 after subtracting 486 from 532.
Take the next digit (7) from the dividend and append it to 46, then repeat: 467 / 81

On to step 4:
The number 81 fits into 467 5 times, leaving a remainder of 62.
Put 5 as the next digit of the answer. 
Result so far: 65.0
If we subtract 405 from 467, we get 62.
Fetch the next digit (6) from the dividend, attach it to 62 and continue: 626 / 81

Advancing to step 5:
The number 81 fits into 626 7 times, leaving a remainder of 59.
The next digit of our result is 7. 
Result so far: 657.0
If we take 567 away from 626, 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.

Step 6:
81 goes into 590 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 657.7
Subtracting 567 from 590 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
The number 81 fits into 230 2 times, leaving a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 657.72
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.

Moving on to step 8:
81 goes into 680 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 657.728
The remainder is 32 after subtracting 648 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
81 can be fit into 320 3 times, resulting in a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 657.7283
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.

Advancing to step 10:
If we divide 770 by 81, we get 9 and a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 657.72839
Subtract 729 from 770 to 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.

On to step 11:
When dividing 410 by 81, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 657.728395
If we subtract 405 from 410, we 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.

Moving on to step 12:
If we divide 50 by 81, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 657.728395
If we subtract 0 from 50, we get 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 13:
When dividing 500 by 81, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 657.72839506
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 657.72839506, and the remainder is 1.4e-08.
