63393461 divided by 15 
Our goal is to divide 63393461 by 15.

Going ahead to step 1:
6 divided by 15 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 15

Step 2:
15 can be fit into 63 4 times, resulting in 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.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 15

Advancing to step 3:
When dividing 33 by 15, we get 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 30 from 33 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 15

On to step 4:
15 can be fit into 39 2 times, resulting in a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 422.0
The remainder is 9 after subtracting 30 from 39.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 15

Step 5:
The number 15 fits into 93 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 4226.0
Subtracting 90 from 93 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 15

On to step 6:
If we divide 34 by 15, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 42262.0
The remainder is 4 after subtracting 30 from 34.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 15

Advancing to step 7:
The number 15 fits into 46 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 422623.0
If we take 45 away from 46, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 15

Step 8:
If we divide 11 by 15, we get 0 and a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 4226230.0
If we subtract 0 from 11, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
When dividing 110 by 15, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 4226230.7
Deduct 105 from 110 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.

On to step 10:
50 divided by 15 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 4226230.73
Subtracting 45 from 50 leaves us 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.

Going ahead to step 11:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 4226230.733
If we take 45 away from 50, we end up 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.

The quotient of the division is 4226230.733, and the remainder is 0.0005.
