895535 divided by 81 
The aim is to understand the frequency of 81 in 895535.

Step 1:
If we divide 8 by 81, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 81

Step 2:
89 divided by 81 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 8 after subtracting 81 from 89.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 81

Advancing to step 3:
When dividing 85 by 81, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 4 after subtracting 81 from 85.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 81

Going ahead to step 4:
81 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 110.0
Subtracting 0 from 45 leaves us with 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 81

On to step 5:
453 divided by 81 is 5 with a remainder of 48.
Record the quotient 5 as the next digit in the result. 
Result so far: 1105.0
Subtract 405 from 453 to get 48.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 81

Step 6:
485 divided by 81 is 5 with a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 11055.0
The remainder is 80 after subtracting 405 from 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 7:
81 can be fit into 800 9 times, resulting in a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 11055.9
The remainder is 71 after subtracting 729 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 8:
81 goes into 710 8 times with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 11055.98
Subtract 648 from 710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
The number 81 fits into 620 7 times, leaving a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 11055.987
Subtracting 567 from 620 leaves us 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.

Advancing to step 10:
81 goes into 530 6 times with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 11055.9876
The remainder is 44 after subtracting 486 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
When dividing 440 by 81, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 11055.98765
The remainder is 35 after subtracting 405 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
350 divided by 81 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 11055.987654
Subtract 324 from 350 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
260 divided by 81 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 11055.9876543
Subtracting 243 from 260 leaves us 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.

Advancing to step 14:
81 goes into 170 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 11055.98765432
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 11055.98765432 and a remainder of 8e-09.
