895865 ÷ 81 
The aim is to understand the frequency of 81 in 895865.

On to step 1:
8 divided by 81 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 81

On to step 2:
If we divide 89 by 81, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 81 from 89 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 81

Let's proceed to step 3:
The number 81 fits into 85 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 81 from 85 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 81

On to step 4:
81 goes into 48 0 times with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Subtract 0 from 48 to get 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 81

Advancing to step 5:
81 goes into 486 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 1106.0
If we take 486 away from 486, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 81

Moving on to step 6:
The number 81 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 11060.0
Deduct 0 from 5 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 81 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 11060.0
If we take 0 away from 50, we end up 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 8:
81 goes into 500 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 11060.06
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.

Let's proceed to step 9:
81 goes into 140 1 times with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 11060.061
Subtracting 81 from 140 leaves us 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.

Let's proceed to step 10:
81 goes into 590 7 times with a remainder of 23.
The next digit of our result is 7. 
Result so far: 11060.0617
The remainder is 23 after subtracting 567 from 590.
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 11:
81 goes into 230 2 times with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 11060.06172
If we subtract 162 from 230, we 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.

Moving on to step 12:
When dividing 680 by 81, we get 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 11060.061728
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.

Let's proceed to step 13:
81 goes into 320 3 times with a remainder of 77.
The next digit of our result is 3. 
Result so far: 11060.0617283
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.

Let's proceed to step 14:
81 can be fit into 770 9 times, resulting in a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 11060.06172839
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.

The final outcome is 11060.06172839, with a leftover of 4.1e-08.
