We divide 36247 by 81
The aim is to understand the frequency of 81 in 36247.

Step 1:
81 goes into 3 0 times with 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.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 81

Moving on to step 2:
If we divide 36 by 81, we get 0 and a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 81

Let's proceed to step 3:
When dividing 362 by 81, we get 4 with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 324 away from 362, we end up with 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 81

Moving on to step 4:
384 divided by 81 is 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtracting 324 from 384 leaves us with 60.
Take the next digit (7) from the dividend and append it to 60, then repeat: 607 / 81

Moving on to step 5:
If we divide 607 by 81, we get 7 and a remainder of 40.
The next digit of our result is 7. 
Result so far: 447.0
Subtracting 567 from 607 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.

On to step 6:
If we divide 400 by 81, we get 4 and a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 447.4
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.

Step 7:
760 divided by 81 is 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 447.49
Deduct 729 from 760 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 8:
81 goes into 310 3 times with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 447.493
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.

Step 9:
The number 81 fits into 670 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 447.4938
The remainder is 22 after subtracting 648 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
The number 81 fits into 220 2 times, leaving a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 447.49382
The remainder is 58 after subtracting 162 from 220.
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:
The number 81 fits into 580 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 447.493827
If we take 567 away from 580, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
81 goes into 130 1 times with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 447.4938271
If we subtract 81 from 130, we get 49.
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 13:
81 can be fit into 490 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 447.49382716
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.

In conclusion, the division gives 447.49382716 with a balance of 4e-09.
