We're dividing 556404 by 8 
We want to figure out the number of times 556404 can be divided by 8.

Step 1:
If we divide 5 by 8, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 8

Advancing to step 2:
55 divided by 8 is 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 48 from 55 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 8

Moving on to step 3:
8 goes into 76 9 times with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we subtract 72 from 76, we get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 8

Step 4:
44 divided by 8 is 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 695.0
Deduct 40 from 44 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 8

Step 5:
40 divided by 8 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6955.0
Subtract 40 from 40 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 8

Moving on to step 6:
8 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 69550.0
Subtract 0 from 4 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.

On to step 7:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 69550.5
If we subtract 40 from 40, we 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.

Advancing to step 8:
When dividing 0 by 8, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 69550.5
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.

On to step 9:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 69550.5
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.

The final outcome is 69550.5, with a leftover of 0.0.
