We look at the division of 631289 by 15 
Our goal is to divide 631289 by 15.

Advancing to step 1:
15 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 15

Let's proceed to step 2:
63 divided by 15 is 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 60 from 63 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 15

Step 3:
31 divided by 15 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 42.0
If we take 30 away from 31, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 15

Step 4:
The number 15 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 420.0
Subtract 0 from 12 to get 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 15

Going ahead to step 5:
128 divided by 15 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 4208.0
Deduct 120 from 128 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 15

Let's proceed to step 6:
89 divided by 15 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 42085.0
Deduct 75 from 89 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
The number 15 fits into 140 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 42085.9
Deduct 135 from 140 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 42085.93
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 42085.933
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 42085.933 and a remainder of 0.0005.
