We look at the division of 940819 by 81 
The aim is to understand the frequency of 81 in 940819.

Advancing to step 1:
The number 81 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
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

Advancing to step 2:
The number 81 fits into 94 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
If we take 81 away from 94, we end up with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 81

Going ahead to step 3:
81 can be fit into 130 1 times, resulting in a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 81 from 130, we get 49.
Bring next digit (8) of the dividend behind the 49 and repeat the process: 498 / 81

Advancing to step 4:
81 can be fit into 498 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 116.0
Deduct 486 from 498 and we're left with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 81

On to step 5:
The number 81 fits into 121 1 times, leaving a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 1161.0
The remainder is 40 after subtracting 81 from 121.
Bring next digit (9) of the dividend behind the 40 and repeat the process: 409 / 81

Let's proceed to step 6:
The number 81 fits into 409 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 11615.0
If we subtract 405 from 409, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 81 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 11615.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
The number 81 fits into 400 4 times, leaving a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 11615.04
The remainder is 76 after subtracting 324 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
When dividing 760 by 81, we get 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 11615.049
The remainder is 31 after subtracting 729 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 10:
When dividing 310 by 81, we get 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 11615.0493
If we take 243 away from 310, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 11:
The number 81 fits into 670 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 11615.04938
Subtract 648 from 670 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
The number 81 fits into 220 2 times, leaving a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 11615.049382
Deduct 162 from 220 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
When dividing 580 by 81, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 11615.0493827
Deduct 567 from 580 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 14:
130 divided by 81 is 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 11615.04938271
If we subtract 81 from 130, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

In conclusion, the division gives 11615.04938271 with a balance of 4.9e-08.
