We divide 947085 by 81
The aim is to understand the frequency of 81 in 947085.

Step 1:
81 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 81

Going ahead to step 2:
If we divide 94 by 81, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 81 from 94 leaves us with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 81

Moving on to step 3:
When dividing 137 by 81, we get 1 with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 56 after subtracting 81 from 137.
Bring next digit (0) of the dividend behind the 56 and repeat the process: 560 / 81

Step 4:
When dividing 560 by 81, we get 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
If we take 486 away from 560, we end up with 74.
Include the next digit (8) from the dividend after 74, then repeat: 748 / 81

On to step 5:
748 divided by 81 is 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 1169.0
If we subtract 729 from 748, we get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 81

Step 6:
195 divided by 81 is 2 with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 11692.0
Subtract 162 from 195 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 7:
81 can be fit into 330 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 11692.4
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.

Moving on to step 8:
If we divide 60 by 81, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 11692.4
If we take 0 away from 60, we end up with 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 9:
If we divide 600 by 81, we get 7 and a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 11692.407
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 10:
81 goes into 330 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 11692.4074
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.

On to step 11:
The number 81 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 11692.4074
Subtract 0 from 60 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 12:
If we divide 600 by 81, we get 7 and a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 11692.407407
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.

Moving on to step 13:
If we divide 330 by 81, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 11692.4074074
Subtract 324 from 330 to get 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 14:
60 divided by 81 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 11692.4074074
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.

After the division, we end up with 11692.4074074 and a remainder of 6e-08.
