We're dividing 443089 by 81 
The aim is to understand the frequency of 81 in 443089.

Moving on to step 1:
4 divided by 81 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 81

Going ahead to step 2:
81 goes into 44 0 times with a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 81

Step 3:
The number 81 fits into 443 5 times, leaving a remainder of 38.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 405 from 443 and we're left with 38.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 81

On to step 4:
The number 81 fits into 380 4 times, leaving a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtracting 324 from 380 leaves us with 56.
Bring next digit (8) of the dividend behind the 56 and repeat the process: 568 / 81

Moving on to step 5:
If we divide 568 by 81, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 547.0
Deduct 567 from 568 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 81

Let's proceed to step 6:
81 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 5470.0
Deduct 0 from 19 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
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: 5470.2
Deduct 162 from 190 and we're left 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.

Moving on to step 8:
When dividing 280 by 81, we get 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 5470.23
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.

Advancing to step 9:
81 can be fit into 370 4 times, resulting in a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 5470.234
Deduct 324 from 370 and we're left 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.

Advancing to step 10:
If we divide 460 by 81, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 5470.2345
Subtract 405 from 460 to 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.

Step 11:
550 divided by 81 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 5470.23456
If we subtract 486 from 550, 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.

Step 12:
If we divide 640 by 81, we get 7 and a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 5470.234567
Deduct 567 from 640 and we're left 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.

Going ahead to step 13:
When dividing 730 by 81, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 5470.2345679
Subtract 729 from 730 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
When dividing 10 by 81, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 5470.2345679
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 5470.2345679 with a balance of 1e-08.
