We divide 345432 by 15
We want to figure out the number of times 345432 can be divided by 15.

Advancing to step 1:
When dividing 3 by 15, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 15

On to step 2:
34 divided by 15 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 4 after subtracting 30 from 34.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 15

Let's proceed to step 3:
When dividing 45 by 15, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 45 from 45 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 15

Let's proceed to step 4:
15 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 15

Step 5:
15 can be fit into 43 2 times, resulting in a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2302.0
If we take 30 away from 43, we end up with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 15

Moving on to step 6:
15 can be fit into 132 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 23028.0
Subtract 120 from 132 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
The number 15 fits into 120 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 23028.8
If we subtract 120 from 120, 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:
When dividing 0 by 15, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23028.8
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:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23028.8
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.

After the division, we end up with 23028.8 and a remainder of 0.0.
