We divide 33240085 by 81
The aim is to understand the frequency of 81 in 33240085.

On to step 1:
When dividing 3 by 81, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 81

Let's proceed to step 2:
The number 81 fits into 33 0 times, leaving a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Fetch the next digit (2) from the dividend, attach it to 33 and continue: 332 / 81

Advancing to step 3:
When dividing 332 by 81, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 324 from 332, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 81

On to step 4:
If we divide 84 by 81, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we take 81 away from 84, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 81

Going ahead to step 5:
81 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 410.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 81

Let's proceed to step 6:
When dividing 300 by 81, we get 3 with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 4103.0
Deduct 243 from 300 and we're left with 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 81

Advancing to step 7:
The number 81 fits into 578 7 times, leaving a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 41037.0
The remainder is 11 after subtracting 567 from 578.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 81

On to step 8:
The number 81 fits into 115 1 times, leaving a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 410371.0
The remainder is 34 after subtracting 81 from 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
The number 81 fits into 340 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 410371.4
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
If we divide 160 by 81, we get 1 and a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 410371.41
Deduct 81 from 160 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 11:
81 goes into 790 9 times with a remainder of 61.
The next digit of our result is 9. 
Result so far: 410371.419
The remainder is 61 after subtracting 729 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
If we divide 610 by 81, we get 7 and a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 410371.4197
If we take 567 away from 610, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 13:
When dividing 430 by 81, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 410371.41975
Deduct 405 from 430 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 14:
The number 81 fits into 250 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 410371.419753
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 15:
81 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 410371.419753
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 16:
The number 81 fits into 700 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 410371.41975308
The remainder is 52 after subtracting 648 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 410371.41975308, with a leftover of 5.2e-08.
