We divide 44899969 by 81
The aim is to understand the frequency of 81 in 44899969.

Step 1:
4 divided by 81 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 81

Going ahead to step 2:
If we divide 44 by 81, we get 0 and a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 81

Let's proceed to step 3:
448 divided by 81 is 5 with a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 405 from 448 leaves us with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 81

Let's proceed to step 4:
The number 81 fits into 439 5 times, leaving a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 55.0
Subtract 405 from 439 to get 34.
Bring next digit (9) of the dividend behind the 34 and repeat the process: 349 / 81

Advancing to step 5:
If we divide 349 by 81, we get 4 and a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 554.0
The remainder is 25 after subtracting 324 from 349.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 81

Let's proceed to step 6:
The number 81 fits into 259 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 5543.0
The remainder is 16 after subtracting 243 from 259.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 81

Advancing to step 7:
The number 81 fits into 166 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 55432.0
Subtract 162 from 166 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 81

Step 8:
If we divide 49 by 81, we get 0 and a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 554320.0
Deduct 0 from 49 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
If we divide 490 by 81, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 554320.6
Subtract 486 from 490 to 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.

Moving on to step 10:
When dividing 40 by 81, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 554320.6
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
81 goes into 400 4 times with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 554320.604
If we take 324 away from 400, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
81 goes into 760 9 times with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 554320.6049
If we subtract 729 from 760, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
310 divided by 81 is 3 with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 554320.60493
Subtracting 243 from 310 leaves us 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.

Advancing to step 14:
When dividing 670 by 81, we get 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 554320.604938
If we subtract 648 from 670, we 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.

Step 15:
The number 81 fits into 220 2 times, leaving a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 554320.6049382
Subtracting 162 from 220 leaves us 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.

Step 16:
When dividing 580 by 81, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 554320.60493827
The remainder is 13 after subtracting 567 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 554320.60493827, with a leftover of 1.3e-08.
