356099 ÷ 30 
We want to figure out the number of times 356099 can be divided by 30.

On to step 1:
If we divide 3 by 30, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 30

Moving on to step 2:
When dividing 35 by 30, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 30 from 35, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 30

Step 3:
The number 30 fits into 56 1 times, leaving a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 30 from 56 leaves us with 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 30

Advancing to step 4:
The number 30 fits into 260 8 times, leaving a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Deduct 240 from 260 and we're left with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 30

Advancing to step 5:
30 goes into 209 6 times with a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 1186.0
Subtract 180 from 209 to get 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 30

Moving on to step 6:
The number 30 fits into 299 9 times, leaving a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 11869.0
Subtract 270 from 299 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
290 divided by 30 is 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 11869.9
Deduct 270 from 290 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
30 goes into 200 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 11869.96
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 11869.966
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 11869.966 with a remaining 0.002.
