We look at the division of 8168658 by 408 
We want to divide 8168658 by 408.

Advancing to step 1:
8 divided by 408 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 408

Advancing to step 2:
408 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (6) from the dividend after 81, then repeat: 816 / 408

Going ahead to step 3:
408 goes into 816 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 816 from 816 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 408

Moving on to step 4:
The number 408 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 408

Advancing to step 5:
If we divide 86 by 408, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 200.0
If we take 0 away from 86, we end up with 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 408

Moving on to step 6:
865 divided by 408 is 2 with a remainder of 49.
The next digit of our result is 2. 
Result so far: 2002.0
If we subtract 816 from 865, we get 49.
Fetch the next digit (8) from the dividend, attach it to 49 and continue: 498 / 408

Advancing to step 7:
408 can be fit into 498 1 times, resulting in a remainder of 90.
Record the quotient 1 as the next digit in the result. 
Result so far: 20021.0
Subtract 408 from 498 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 8:
When dividing 900 by 408, we get 2 with a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 20021.2
Deduct 816 from 900 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 9:
If we divide 840 by 408, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 20021.22
If we subtract 816 from 840, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 20021.22, with a leftover of 0.024.
