We divide 230925 by 15
We want to figure out the number of times 230925 can be divided by 15.

Step 1:
2 divided by 15 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 15

On to step 2:
When dividing 23 by 15, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 15 away from 23, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 15

On to step 3:
When dividing 80 by 15, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 75 away from 80, we end up with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 15

On to step 4:
The number 15 fits into 59 3 times, leaving a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 153.0
If we take 45 away from 59, we end up with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 15

Let's proceed to step 5:
142 divided by 15 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 1539.0
The remainder is 7 after subtracting 135 from 142.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 15

On to step 6:
15 can be fit into 75 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15395.0
If we subtract 75 from 75, 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 7:
15 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15395.0
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.

Advancing to step 8:
15 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15395.0
Deduct 0 from 0 and we're left 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.

After the division, we end up with 15395.0 and a remainder of 0.0.
