896244 ÷ 81 
The aim is to understand the frequency of 81 in 896244.

On to step 1:
8 divided by 81 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 81

Going ahead to step 2:
81 goes into 89 1 times with 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.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 81

On to step 3:
The number 81 fits into 86 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 81 from 86 leaves us with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 81

Moving on to step 4:
When dividing 52 by 81, we get 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 110.0
Deduct 0 from 52 and we're left with 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 81

Moving on to step 5:
81 can be fit into 524 6 times, resulting in a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 1106.0
The remainder is 38 after subtracting 486 from 524.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 81

Moving on to step 6:
384 divided by 81 is 4 with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 11064.0
Subtract 324 from 384 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
81 can be fit into 600 7 times, resulting in a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 11064.7
Subtract 567 from 600 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 8:
81 can be fit into 330 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 11064.74
The remainder is 6 after subtracting 324 from 330.
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 9:
The number 81 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 11064.74
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.

Moving on to step 10:
When dividing 600 by 81, we get 7 with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 11064.7407
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 11:
The number 81 fits into 330 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 11064.74074
If we take 324 away from 330, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
When dividing 60 by 81, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 11064.74074
If we subtract 0 from 60, we get 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 13:
81 can be fit into 600 7 times, resulting in a remainder of 33.
The next digit of our result is 7. 
Result so far: 11064.7407407
If we subtract 567 from 600, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 14:
330 divided by 81 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 11064.74074074
Subtracting 324 from 330 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 11064.74074074, with a leftover of 6e-09.
