594409 ÷ 8 
The aim is to understand the frequency of 8 in 594409.

Advancing to step 1:
The number 8 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 8

Let's proceed to step 2:
8 goes into 59 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 3 after subtracting 56 from 59.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 8

Moving on to step 3:
If we divide 34 by 8, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
The remainder is 2 after subtracting 32 from 34.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 8

Step 4:
If we divide 24 by 8, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 743.0
If we subtract 24 from 24, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 8

On to step 5:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7430.0
If we subtract 0 from 0, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 8

Let's proceed to step 6:
9 divided by 8 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 74301.0
Deduct 8 from 9 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 8, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 74301.1
Subtracting 8 from 10 leaves us 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.

Moving on to step 8:
20 divided by 8 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 74301.12
If we subtract 16 from 20, we 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.

Step 9:
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: 74301.125
Subtract 40 from 40 to 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.

Advancing to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 74301.125
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.

Going ahead to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 74301.125
The remainder is 0 after subtracting 0 from 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 74301.125, and the remainder is 0.0.
