We divide 976275 by 81
The aim is to understand the frequency of 81 in 976275.

Advancing to step 1:
81 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 81

Step 2:
81 can be fit into 97 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 81 from 97, we get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 81

Advancing to step 3:
If we divide 166 by 81, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 162 away from 166, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 81

Moving on to step 4:
When dividing 42 by 81, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 81

Going ahead to step 5:
The number 81 fits into 427 5 times, leaving a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 1205.0
Subtract 405 from 427 to get 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 81

Going ahead to step 6:
If we divide 225 by 81, we get 2 and a remainder of 63.
Put 2 as the next digit of the answer. 
Result so far: 12052.0
If we take 162 away from 225, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
The number 81 fits into 630 7 times, leaving a remainder of 63.
The next digit of our result is 7. 
Result so far: 12052.7
If we take 567 away from 630, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 8:
81 goes into 630 7 times with a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 12052.77
If we subtract 567 from 630, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final result is 12052.77 with a remainder of 0.063.
