687432 ÷ 15 
Our goal is to divide 687432 by 15.

Going ahead to step 1:
When dividing 6 by 15, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 15

Step 2:
68 divided by 15 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 8 after subtracting 60 from 68.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 15

Moving on to step 3:
15 goes into 87 5 times with a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 75 away from 87, we end up with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 15

Going ahead to step 4:
If we divide 124 by 15, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 458.0
Subtracting 120 from 124 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 15

Moving on to step 5:
When dividing 43 by 15, we get 2 with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 4582.0
The remainder is 13 after subtracting 30 from 43.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 15

Let's proceed to step 6:
The number 15 fits into 132 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 45828.0
If we take 120 away from 132, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
120 divided by 15 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 45828.8
Deduct 120 from 120 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.

On to step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 45828.8
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.

Going ahead to step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 45828.8
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.

The final result is 45828.8 with a remainder of 0.0.
