353100 ÷ 15 
We want to figure out the number of times 353100 can be divided by 15.

Step 1:
When dividing 3 by 15, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 15

Advancing to step 2:
15 can be fit into 35 2 times, resulting in a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 5 after subtracting 30 from 35.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 15

Moving on to step 3:
If we divide 53 by 15, we get 3 and a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
The remainder is 8 after subtracting 45 from 53.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 15

Advancing to step 4:
81 divided by 15 is 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 235.0
Subtract 75 from 81 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 15

Going ahead to step 5:
If we divide 60 by 15, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 2354.0
The remainder is 0 after subtracting 60 from 60.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 15

Advancing to step 6:
If we divide 0 by 15, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23540.0
Subtract 0 from 0 to 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.

Step 7:
15 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 23540.0
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 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 23540.0
The remainder is 0 after subtracting 0 from 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 quotient of the division is 23540.0, and the remainder is 0.0.
