406998 ÷ 8 
The aim is to understand the frequency of 8 in 406998.

Going ahead to step 1:
The number 8 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 8

Step 2:
40 divided by 8 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 40 from 40 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 8

On to step 3:
When dividing 6 by 8, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 8

On to step 4:
8 goes into 69 8 times with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 508.0
If we take 64 away from 69, we end up with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 8

Let's proceed to step 5:
8 can be fit into 59 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 5087.0
Deduct 56 from 59 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 8

Going ahead to step 6:
8 goes into 38 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 50874.0
If we subtract 32 from 38, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 8 fits into 60 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 50874.7
Subtract 56 from 60 to 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.

Advancing to step 8:
8 goes into 40 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 50874.75
If we take 40 away from 40, we end up 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 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50874.75
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.

Advancing 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: 50874.75
Subtract 0 from 0 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.

The quotient of the division is 50874.75, and the remainder is 0.0.
