We're dividing 30122508 by 599 
We want to figure out the number of times 30122508 can be divided by 599.

Going ahead to step 1:
The number 599 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 599

Step 2:
When dividing 30 by 599, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 599

Advancing to step 3:
301 divided by 599 is 0 with a remainder of 301.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 301 to get 301.
Grab the next digit (2) from the dividend, add it to 301, then carry on: 3012 / 599

Step 4:
If we divide 3012 by 599, we get 5 and a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 2995 from 3012, we get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 599

Step 5:
The number 599 fits into 172 0 times, leaving a remainder of 172.
The next digit of our result is 0. 
Result so far: 50.0
Subtract 0 from 172 to get 172.
Take the next digit (5) from the dividend and append it to 172, then repeat: 1725 / 599

Let's proceed to step 6:
When dividing 1725 by 599, we get 2 with a remainder of 527.
Record the quotient 2 as the next digit in the result. 
Result so far: 502.0
If we subtract 1198 from 1725, we get 527.
Bring next digit (0) of the dividend behind the 527 and repeat the process: 5270 / 599

Let's proceed to step 7:
If we divide 5270 by 599, we get 8 and a remainder of 478.
Use 8 as the next digit of our solution. 
Result so far: 5028.0
Subtract 4792 from 5270 to get 478.
Append the next digit (8) from the dividend to 478 and continue with: 4788 / 599

Step 8:
The number 599 fits into 4788 7 times, leaving a remainder of 595.
Record the quotient 7 as the next digit in the result. 
Result so far: 50287.0
Deduct 4193 from 4788 and we're left with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 9:
The number 599 fits into 5950 9 times, leaving a remainder of 559.
Write down 9 as next digit of the result. 
Result so far: 50287.9
Subtracting 5391 from 5950 leaves us with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Let's proceed to step 10:
5590 divided by 599 is 9 with a remainder of 199.
Write down 9 as next digit of the result. 
Result so far: 50287.99
Subtracting 5391 from 5590 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

After the division, we end up with 50287.99 and a remainder of 0.199.
