Let's divide 353343 by 30
Let's see how many times 30 fits into 353343.

Advancing to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 30

Step 2:
The number 30 fits into 35 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 30 from 35 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 30

Step 3:
When dividing 53 by 30, we get 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 23 after subtracting 30 from 53.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 30

Advancing to step 4:
30 goes into 233 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Deduct 210 from 233 and we're left with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 30

Going ahead to step 5:
234 divided by 30 is 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 1177.0
If we subtract 210 from 234, we get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 30

Going ahead to step 6:
The number 30 fits into 243 8 times, leaving a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 11778.0
Subtracting 240 from 243 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 30, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 11778.1
If we subtract 30 from 30, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11778.1
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 11778.1
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 11778.1 with a remainder of 0.0.
