We're dividing 663594 by 6 
Our goal is to divide 663594 by 6.

Going ahead to step 1:
6 goes into 6 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 6 from 6, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 6

Advancing to step 2:
6 divided by 6 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 6 from 6 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 6

Going ahead to step 3:
6 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 6

Let's proceed to step 4:
When dividing 35 by 6, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1105.0
Subtract 30 from 35 to get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 6

Advancing to step 5:
59 divided by 6 is 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 11059.0
Deduct 54 from 59 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 6

Step 6:
The number 6 fits into 54 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 110599.0
The remainder is 0 after subtracting 54 from 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
6 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 110599.0
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.

Going ahead to step 8:
0 divided by 6 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 110599.0
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.

The final result is 110599.0 with a remainder of 0.0.
