We look at the division of 15992006 by 963 
Let's see how many times 963 fits into 15992006.

Step 1:
963 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 963

Advancing to step 2:
When dividing 15 by 963, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 963

On to step 3:
The number 963 fits into 159 0 times, leaving a remainder of 159.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 159 leaves us with 159.
Fetch the next digit (9) from the dividend, attach it to 159 and continue: 1599 / 963

Step 4:
When dividing 1599 by 963, we get 1 with a remainder of 636.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 963 away from 1599, we end up with 636.
Fetch the next digit (2) from the dividend, attach it to 636 and continue: 6362 / 963

Step 5:
6362 divided by 963 is 6 with a remainder of 584.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 5778 from 6362 to get 584.
Fetch the next digit (0) from the dividend, attach it to 584 and continue: 5840 / 963

Moving on to step 6:
The number 963 fits into 5840 6 times, leaving a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 166.0
The remainder is 62 after subtracting 5778 from 5840.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 963

Advancing to step 7:
The number 963 fits into 620 0 times, leaving a remainder of 620.
Put 0 as the next digit of the answer. 
Result so far: 1660.0
Deduct 0 from 620 and we're left with 620.
Grab the next digit (6) from the dividend, add it to 620, then carry on: 6206 / 963

Going ahead to step 8:
When dividing 6206 by 963, we get 6 with a remainder of 428.
Write down 6 as next digit of the result. 
Result so far: 16606.0
Subtract 5778 from 6206 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 9:
963 can be fit into 4280 4 times, resulting in a remainder of 428.
Record the quotient 4 as the next digit in the result. 
Result so far: 16606.4
Subtract 3852 from 4280 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 10:
When dividing 4280 by 963, we get 4 with a remainder of 428.
The next digit of our result is 4. 
Result so far: 16606.44
Deduct 3852 from 4280 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

After the division, we end up with 16606.44 and a remainder of 0.428.
