We look at the division of 409877 by 1 
Our goal is to divide 409877 by 1.

Advancing to step 1:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 4 away from 4, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Moving on to step 2:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Advancing to step 3:
1 goes into 9 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 409.0
Subtract 9 from 9 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Step 4:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 4098.0
Subtracting 8 from 8 leaves us with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

On to step 5:
7 divided by 1 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 40987.0
Subtract 7 from 7 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Step 6:
1 can be fit into 7 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 409877.0
If we take 7 away from 7, 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.

Going ahead to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 409877.0
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.

Moving on to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 409877.0
If we take 0 away from 0, 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.

In conclusion, the division gives 409877.0 with a balance of 0.0.
