We're dividing 308002 by 81 
The aim is to understand the frequency of 81 in 308002.

Going ahead to step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 81

Let's proceed to step 2:
30 divided by 81 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 81

Moving on to step 3:
308 divided by 81 is 3 with a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 243 from 308, we get 65.
Fetch the next digit (0) from the dividend, attach it to 65 and continue: 650 / 81

On to step 4:
81 can be fit into 650 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 648 from 650 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 81

On to step 5:
When dividing 20 by 81, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 380.0
If we subtract 0 from 20, we get 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 81

Advancing to step 6:
81 can be fit into 202 2 times, resulting in a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 3802.0
Subtracting 162 from 202 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.

Moving on to step 7:
When dividing 400 by 81, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 3802.4
The remainder is 76 after subtracting 324 from 400.
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 8:
760 divided by 81 is 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 3802.49
Subtract 729 from 760 to 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.

Moving on to step 9:
81 can be fit into 310 3 times, resulting in a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 3802.493
Subtract 243 from 310 to 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 10:
81 can be fit into 670 8 times, resulting in a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 3802.4938
Subtracting 648 from 670 leaves us 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.

On to step 11:
220 divided by 81 is 2 with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 3802.49382
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.

On to step 12:
The number 81 fits into 580 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 3802.493827
If we subtract 567 from 580, we 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.

Moving on to step 13:
The number 81 fits into 130 1 times, leaving a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 3802.4938271
The remainder is 49 after subtracting 81 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 14:
The number 81 fits into 490 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 3802.49382716
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.

The quotient of the division is 3802.49382716, and the remainder is 4e-09.
