Let's divide 20392381 by 8
The aim is to understand the frequency of 8 in 20392381.

Moving on to step 1:
If we divide 2 by 8, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 8

Step 2:
When dividing 20 by 8, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 16 from 20 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 8

Let's proceed to step 3:
43 divided by 8 is 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 25.0
The remainder is 3 after subtracting 40 from 43.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 8

Moving on to step 4:
When dividing 39 by 8, we get 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
If we take 32 away from 39, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 8

On to step 5:
72 divided by 8 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 2549.0
Subtract 72 from 72 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 8

Step 6:
8 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 25490.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 8

Advancing to step 7:
8 goes into 38 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 254904.0
If we take 32 away from 38, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 8

Let's proceed to step 8:
The number 8 fits into 61 7 times, leaving a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 2549047.0
The remainder is 5 after subtracting 56 from 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
50 divided by 8 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 2549047.6
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
8 goes into 20 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2549047.62
Deduct 16 from 20 and we're left 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.

Moving on to step 11:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2549047.625
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2549047.625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
8 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2549047.625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 2549047.625, and the remainder is 0.0.
