We look at the division of 408916 by 1 
Our goal is to divide 408916 by 1.

Step 1:
1 goes into 4 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 4 from 4, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Let's proceed to step 2:
When dividing 0 by 1, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 0 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

On to step 3:
When dividing 8 by 1, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 408.0
Subtract 8 from 8 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Advancing to step 4:
9 divided by 1 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 4089.0
Subtracting 9 from 9 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Let's proceed to step 5:
The number 1 fits into 1 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 40891.0
Deduct 1 from 1 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Moving on to step 6:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 408916.0
If we take 6 away from 6, 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.

Advancing to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 408916.0
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 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 408916.0
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 final outcome is 408916.0, with a leftover of 0.0.
