940311 ÷ 81 
The aim is to understand the frequency of 81 in 940311.

Advancing to step 1:
81 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 81

Moving on to step 2:
94 divided by 81 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 81 from 94 leaves us with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 81

Let's proceed to step 3:
The number 81 fits into 130 1 times, leaving a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 81 from 130, we get 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 81

Moving on to step 4:
When dividing 493 by 81, we get 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Subtracting 486 from 493 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 81

Step 5:
81 can be fit into 71 0 times, resulting in a remainder of 71.
The next digit of our result is 0. 
Result so far: 1160.0
Deduct 0 from 71 and we're left with 71.
Fetch the next digit (1) from the dividend, attach it to 71 and continue: 711 / 81

Going ahead to step 6:
81 goes into 711 8 times with a remainder of 63.
Use 8 as the next digit of our solution. 
Result so far: 11608.0
Subtract 648 from 711 to 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.

Moving on to step 7:
When dividing 630 by 81, we get 7 with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 11608.7
The remainder is 63 after subtracting 567 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 8:
81 can be fit into 630 7 times, resulting in a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 11608.77
Deduct 567 from 630 and we're left 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.

The final outcome is 11608.77, with a leftover of 0.063.
