Let's divide 382174 by 81
The aim is to understand the frequency of 81 in 382174.

Step 1:
When dividing 3 by 81, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 81

Advancing to step 2:
81 goes into 38 0 times with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Include the next digit (2) from the dividend after 38, then repeat: 382 / 81

Moving on to step 3:
When dividing 382 by 81, we get 4 with a remainder of 58.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 324 from 382 to get 58.
Append the next digit (1) from the dividend to 58 and continue with: 581 / 81

On to step 4:
The number 81 fits into 581 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 567 away from 581, we end up with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 81

On to step 5:
81 can be fit into 147 1 times, resulting in a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 471.0
If we take 81 away from 147, we end up with 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 81

Let's proceed to step 6:
664 divided by 81 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 4718.0
If we take 648 away from 664, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
81 goes into 160 1 times with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 4718.1
Subtract 81 from 160 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 8:
81 goes into 790 9 times with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 4718.19
If we subtract 729 from 790, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
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: 4718.197
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.

Going ahead to step 10:
81 can be fit into 430 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 4718.1975
Subtracting 405 from 430 leaves us 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.

Moving on to step 11:
The number 81 fits into 250 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 4718.19753
If we subtract 243 from 250, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
81 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 4718.19753
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 13:
700 divided by 81 is 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 4718.1975308
Deduct 648 from 700 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 14:
520 divided by 81 is 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 4718.19753086
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 4718.19753086 with a remainder of 3.4e-08.
