We divide 603804 by 8
We want to figure out the number of times 603804 can be divided by 8.

Advancing to step 1:
The number 8 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 8

Advancing to step 2:
The number 8 fits into 60 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 56 from 60 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 8

Advancing to step 3:
The number 8 fits into 43 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we subtract 40 from 43, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 8

Going ahead to step 4:
When dividing 38 by 8, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 754.0
If we take 32 away from 38, we end up with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 8

On to step 5:
60 divided by 8 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 7547.0
Deduct 56 from 60 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 8

Step 6:
8 can be fit into 44 5 times, resulting in a remainder of 4.
The next digit of our result is 5. 
Result so far: 75475.0
Subtract 40 from 44 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.

Going ahead to step 7:
8 goes into 40 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 75475.5
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.

Going ahead to step 8:
0 divided by 8 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 75475.5
If we subtract 0 from 0, 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.

Going ahead to step 9:
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: 75475.5
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.

The final result is 75475.5 with a remainder of 0.0.
