We divide 999603 by 5
Let's see how many times 5 fits into 999603.

Advancing to step 1:
The number 5 fits into 9 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 5 from 9.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 5

Let's proceed to step 2:
5 goes into 49 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 45 from 49 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 5

Going ahead to step 3:
The number 5 fits into 49 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
Subtracting 45 from 49 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 5

Step 4:
If we divide 46 by 5, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 1999.0
If we subtract 45 from 46, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 5

Going ahead to step 5:
5 goes into 10 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 19992.0
The remainder is 0 after subtracting 10 from 10.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 5

Moving on to step 6:
If we divide 3 by 5, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 199920.0
Deduct 0 from 3 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
5 can be fit into 30 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 199920.6
Deduct 30 from 30 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:
When dividing 0 by 5, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 199920.6
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.

Advancing to step 9:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 199920.6
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.

After the division, we end up with 199920.6 and a remainder of 0.0.
