715435 ÷ 8 
The aim is to understand the frequency of 8 in 715435.

Advancing to step 1:
8 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 8

Moving on to step 2:
The number 8 fits into 71 8 times, leaving a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 64 from 71 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 8

Step 3:
8 can be fit into 75 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we subtract 72 from 75, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 8

Let's proceed to step 4:
The number 8 fits into 34 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 894.0
Subtracting 32 from 34 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 8

On to step 5:
The number 8 fits into 23 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 8942.0
The remainder is 7 after subtracting 16 from 23.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 8

Let's proceed to step 6:
8 can be fit into 75 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 89429.0
Subtracting 72 from 75 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
8 goes into 30 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 89429.3
Deduct 24 from 30 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 89429.37
If we subtract 56 from 60, 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:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 89429.375
If we subtract 40 from 40, 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.

Moving on to step 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 89429.375
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.

Step 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 89429.375
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.

The quotient of the division is 89429.375, and the remainder is 0.0.
