718981 ÷ 8 
The aim is to understand the frequency of 8 in 718981.

Going ahead to step 1:
If we divide 7 by 8, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 8

Moving on to step 2:
71 divided by 8 is 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 7 after subtracting 64 from 71.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 8

Going ahead to step 3:
78 divided by 8 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we subtract 72 from 78, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 8

Going ahead to step 4:
If we divide 69 by 8, we get 8 and a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 898.0
The remainder is 5 after subtracting 64 from 69.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 8

On to step 5:
8 can be fit into 58 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 8987.0
Subtract 56 from 58 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 8

Advancing to step 6:
The number 8 fits into 21 2 times, leaving a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 89872.0
If we subtract 16 from 21, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
When dividing 50 by 8, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 89872.6
Deduct 48 from 50 and we're left 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:
If we divide 20 by 8, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 89872.62
The remainder is 4 after subtracting 16 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
40 divided by 8 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 89872.625
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 10:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 89872.625
Subtracting 0 from 0 leaves us 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.

Moving on to step 11:
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: 89872.625
Subtracting 0 from 0 leaves us 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 89872.625, and the remainder is 0.0.
