503199 divided by 66 
We want to figure out the number of times 503199 can be divided by 66.

Going ahead to step 1:
66 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 66

Moving on to step 2:
50 divided by 66 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 66

Let's proceed to step 3:
If we divide 503 by 66, we get 7 and a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 462 from 503, we get 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 66

Let's proceed to step 4:
The number 66 fits into 411 6 times, leaving a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 76.0
The remainder is 15 after subtracting 396 from 411.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 66

Let's proceed to step 5:
When dividing 159 by 66, we get 2 with a remainder of 27.
The next digit of our result is 2. 
Result so far: 762.0
Deduct 132 from 159 and we're left with 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 66

Advancing to step 6:
If we divide 279 by 66, we get 4 and a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 7624.0
If we take 264 away from 279, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
66 can be fit into 150 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 7624.2
If we subtract 132 from 150, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
66 goes into 180 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 7624.22
Deduct 132 from 180 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 7624.22 with a remaining 0.048.
