We're dividing 819473 by 81 
The aim is to understand the frequency of 81 in 819473.

Let's proceed to step 1:
81 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 81

Step 2:
The number 81 fits into 81 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 81 from 81 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 81

Moving on to step 3:
81 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 81

Going ahead to step 4:
81 can be fit into 94 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Deduct 81 from 94 and we're left with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 81

Let's proceed to step 5:
The number 81 fits into 137 1 times, leaving a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 1011.0
The remainder is 56 after subtracting 81 from 137.
Append the next digit (3) from the dividend to 56 and continue with: 563 / 81

Moving on to step 6:
When dividing 563 by 81, we get 6 with a remainder of 77.
Put 6 as the next digit of the answer. 
Result so far: 10116.0
The remainder is 77 after subtracting 486 from 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 7:
770 divided by 81 is 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 10116.9
Deduct 729 from 770 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 8:
410 divided by 81 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 10116.95
Subtracting 405 from 410 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
81 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10116.95
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
500 divided by 81 is 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 10116.9506
If we subtract 486 from 500, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
The number 81 fits into 140 1 times, leaving a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 10116.95061
Subtract 81 from 140 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 12:
590 divided by 81 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 10116.950617
Deduct 567 from 590 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
When dividing 230 by 81, we get 2 with a remainder of 68.
The next digit of our result is 2. 
Result so far: 10116.9506172
If we take 162 away from 230, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 14:
If we divide 680 by 81, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 10116.95061728
Subtracting 648 from 680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 10116.95061728, and the remainder is 3.2e-08.
