53654 divided by 81 
The aim is to understand the frequency of 81 in 53654.

Moving on to step 1:
If we divide 5 by 81, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 81

Going ahead to step 2:
If we divide 53 by 81, we get 0 and a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Bring next digit (6) of the dividend behind the 53 and repeat the process: 536 / 81

Let's proceed to step 3:
81 can be fit into 536 6 times, resulting in a remainder of 50.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 486 from 536 leaves us with 50.
Take the next digit (5) from the dividend and append it to 50, then repeat: 505 / 81

Step 4:
If we divide 505 by 81, we get 6 and a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 66.0
The remainder is 19 after subtracting 486 from 505.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 81

Let's proceed to step 5:
81 can be fit into 194 2 times, resulting in a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 662.0
Deduct 162 from 194 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 6:
The number 81 fits into 320 3 times, leaving a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 662.3
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.

Advancing to step 7:
If we divide 770 by 81, we get 9 and a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 662.39
Deduct 729 from 770 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 8:
If we divide 410 by 81, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 662.395
The remainder is 5 after subtracting 405 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
When dividing 50 by 81, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 662.395
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
If we divide 500 by 81, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 662.39506
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.

On to step 11:
81 can be fit into 140 1 times, resulting in a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 662.395061
Deduct 81 from 140 and we're left 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.

Going ahead to step 12:
If we divide 590 by 81, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 662.3950617
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.

On to step 13:
81 goes into 230 2 times with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 662.39506172
Subtract 162 from 230 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 662.39506172 with a balance of 6.8e-08.
