We're dividing 30841627 by 81 
The aim is to understand the frequency of 81 in 30841627.

Advancing to step 1:
3 divided by 81 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 81

Advancing to step 2:
81 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 81

Going ahead to step 3:
If we divide 308 by 81, we get 3 and a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 243 from 308 and we're left with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 81

Going ahead to step 4:
The number 81 fits into 654 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtract 648 from 654 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 81

Let's proceed to step 5:
When dividing 61 by 81, we get 0 with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 380.0
Subtracting 0 from 61 leaves us with 61.
Take the next digit (6) from the dividend and append it to 61, then repeat: 616 / 81

Step 6:
If we divide 616 by 81, we get 7 and a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 3807.0
Deduct 567 from 616 and we're left with 49.
Append the next digit (2) from the dividend to 49 and continue with: 492 / 81

Step 7:
If we divide 492 by 81, we get 6 and a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 38076.0
Subtract 486 from 492 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 81

Advancing to step 8:
When dividing 67 by 81, we get 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 380760.0
If we subtract 0 from 67, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 9:
81 can be fit into 670 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 380760.8
If we take 648 away from 670, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
If we divide 220 by 81, we get 2 and a remainder of 58.
The next digit of our result is 2. 
Result so far: 380760.82
If we subtract 162 from 220, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
81 goes into 580 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 380760.827
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
81 goes into 130 1 times with a remainder of 49.
The next digit of our result is 1. 
Result so far: 380760.8271
Subtracting 81 from 130 leaves us 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.

Going ahead to step 13:
490 divided by 81 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 380760.82716
Subtracting 486 from 490 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
When dividing 40 by 81, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 380760.82716
If we take 0 away from 40, we end up 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.

On to step 15:
81 can be fit into 400 4 times, resulting in a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 380760.8271604
Subtracting 324 from 400 leaves us 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.

Step 16:
When dividing 760 by 81, we get 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 380760.82716049
The remainder is 31 after subtracting 729 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The quotient of the division is 380760.82716049, and the remainder is 3.1e-08.
