We divide 486405 by 8
We want to divide 486405 by 8.

On to step 1:
8 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 8

On to step 2:
48 divided by 8 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 48 from 48 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 8

Moving on to step 3:
When dividing 6 by 8, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 8

Going ahead to step 4:
8 goes into 64 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 608.0
Deduct 64 from 64 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 8

Step 5:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 6080.0
If we subtract 0 from 0, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 8

Let's proceed to step 6:
8 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 60800.0
If we subtract 0 from 5, 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.

Let's proceed to step 7:
8 can be fit into 50 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 60800.6
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.

Going ahead to step 8:
When dividing 20 by 8, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 60800.62
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.

Advancing to step 9:
8 goes into 40 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 60800.625
Subtract 40 from 40 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.

On to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 60800.625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 60800.625
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.

Our division results in 60800.625 with a remaining 0.0.
