661762 ÷ 15 
Let's see how many times 15 fits into 661762.

Step 1:
If we divide 6 by 15, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 15

Advancing to step 2:
15 goes into 66 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 60 from 66, we get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 15

Going ahead to step 3:
If we divide 61 by 15, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 44.0
The remainder is 1 after subtracting 60 from 61.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 15

Going ahead to step 4:
15 can be fit into 17 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 441.0
Subtracting 15 from 17 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 15

Let's proceed to step 5:
The number 15 fits into 26 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 4411.0
If we subtract 15 from 26, we get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 15

On to step 6:
112 divided by 15 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 44117.0
The remainder is 7 after subtracting 105 from 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
15 can be fit into 70 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 44117.4
Subtract 60 from 70 to 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.

Advancing to step 8:
100 divided by 15 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 44117.46
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:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 44117.466
If we subtract 90 from 100, 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.

Our division results in 44117.466 with a remaining 0.001.
