We divide 481042 by 81
The aim is to understand the frequency of 81 in 481042.

Let's proceed to step 1:
When dividing 4 by 81, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 81

On to step 2:
The number 81 fits into 48 0 times, leaving a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 81

Going ahead to step 3:
If we divide 481 by 81, we get 5 and a remainder of 76.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 405 from 481, we get 76.
Include the next digit (0) from the dividend after 76, then repeat: 760 / 81

Advancing to step 4:
81 can be fit into 760 9 times, resulting in a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 59.0
If we subtract 729 from 760, we get 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 81

Step 5:
81 can be fit into 314 3 times, resulting in a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 593.0
Deduct 243 from 314 and we're left with 71.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 81

Let's proceed to step 6:
81 can be fit into 712 8 times, resulting in a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 5938.0
If we subtract 648 from 712, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 7:
The number 81 fits into 640 7 times, leaving a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 5938.7
Subtracting 567 from 640 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 8:
The number 81 fits into 730 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 5938.79
The remainder is 1 after subtracting 729 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
81 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 5938.79
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
81 can be fit into 100 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 5938.7901
Subtract 81 from 100 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
81 can be fit into 190 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 5938.79012
If we take 162 away from 190, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
81 goes into 280 3 times with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 5938.790123
Deduct 243 from 280 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 13:
When dividing 370 by 81, we get 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 5938.7901234
If we take 324 away from 370, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
If we divide 460 by 81, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 5938.79012345
If we subtract 405 from 460, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

In conclusion, the division gives 5938.79012345 with a balance of 5.5e-08.
