We divide 651661 by 15
Let's see how many times 15 fits into 651661.

Step 1:
15 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 15

Let's proceed to step 2:
When dividing 65 by 15, we get 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 5 after subtracting 60 from 65.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 15

On to step 3:
15 goes into 51 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 45 from 51 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 15

On to step 4:
66 divided by 15 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 434.0
Subtract 60 from 66 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 15

On to step 5:
15 goes into 66 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4344.0
Subtracting 60 from 66 leaves us with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 15

Advancing to step 6:
15 goes into 61 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 43444.0
Deduct 60 from 61 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 15, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 43444.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
15 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 43444.06
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
100 divided by 15 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 43444.066
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 43444.066 and a remainder of 0.001.
