Let's divide 362534 by 81
The aim is to understand the frequency of 81 in 362534.

On to step 1:
When dividing 3 by 81, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 81

Step 2:
If we divide 36 by 81, we get 0 and a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 81

On to step 3:
362 divided by 81 is 4 with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 324 from 362 and we're left with 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 81

Advancing to step 4:
81 can be fit into 385 4 times, resulting in a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 324 away from 385, we end up with 61.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 81

Moving on to step 5:
613 divided by 81 is 7 with a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 447.0
The remainder is 46 after subtracting 567 from 613.
Append the next digit (4) from the dividend to 46 and continue with: 464 / 81

Moving on to step 6:
81 goes into 464 5 times with a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 4475.0
The remainder is 59 after subtracting 405 from 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
81 can be fit into 590 7 times, resulting in a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 4475.7
If we subtract 567 from 590, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
230 divided by 81 is 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 4475.72
Subtract 162 from 230 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
81 goes into 680 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 4475.728
The remainder is 32 after subtracting 648 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
81 can be fit into 320 3 times, resulting in a remainder of 77.
The next digit of our result is 3. 
Result so far: 4475.7283
Deduct 243 from 320 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 11:
When dividing 770 by 81, we get 9 with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 4475.72839
If we subtract 729 from 770, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 12:
410 divided by 81 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4475.728395
The remainder is 5 after subtracting 405 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
50 divided by 81 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 4475.728395
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
500 divided by 81 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 4475.72839506
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 4475.72839506, with a leftover of 1.4e-08.
