353953 ÷ 30 
We want to figure out the number of times 353953 can be divided by 30.

Step 1:
When dividing 3 by 30, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 30

Step 2:
35 divided by 30 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 5 after subtracting 30 from 35.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 30

Going ahead to step 3:
30 goes into 53 1 times with a remainder of 23.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 30 from 53 leaves us with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 30

Moving on to step 4:
The number 30 fits into 239 7 times, leaving a remainder of 29.
The next digit of our result is 7. 
Result so far: 117.0
If we take 210 away from 239, we end up with 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 30

Going ahead to step 5:
295 divided by 30 is 9 with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 1179.0
Deduct 270 from 295 and we're left with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 30

Advancing to step 6:
30 goes into 253 8 times with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 11798.0
The remainder is 13 after subtracting 240 from 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
The number 30 fits into 130 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 11798.4
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 11798.43
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
30 goes into 100 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 11798.433
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 11798.433 with a balance of 0.001.
