We look at the division of 661437 by 15 
Our goal is to divide 661437 by 15.

Let's proceed to step 1:
6 divided by 15 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 15

Going ahead to step 2:
66 divided by 15 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 60 from 66 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 15

On to step 3:
61 divided by 15 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 44.0
The remainder is 1 after subtracting 60 from 61.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 15

Moving on to step 4:
The number 15 fits into 14 0 times, leaving a remainder of 14.
The next digit of our result is 0. 
Result so far: 440.0
Subtracting 0 from 14 leaves us with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 15

Step 5:
15 goes into 143 9 times with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 4409.0
If we take 135 away from 143, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 15

Let's proceed to step 6:
87 divided by 15 is 5 with a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 44095.0
Subtract 75 from 87 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.

Advancing to step 7:
When dividing 120 by 15, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 44095.8
Subtract 120 from 120 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.

Going ahead 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: 44095.8
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.

Let's proceed to step 9:
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: 44095.8
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.

Our division results in 44095.8 with a remaining 0.0.
