Let's divide 63780885 by 16
Our goal is to divide 63780885 by 16.

On to step 1:
When dividing 6 by 16, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 16

Moving on to step 2:
The number 16 fits into 63 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 48 from 63 to get 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 16

Moving on to step 3:
157 divided by 16 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 144 from 157 leaves us with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 16

Step 4:
16 can be fit into 138 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 398.0
Subtracting 128 from 138 leaves us with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 16

On to step 5:
16 can be fit into 100 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 3986.0
If we take 96 away from 100, we end up with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 16

On to step 6:
When dividing 48 by 16, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 39863.0
If we take 48 away from 48, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 16

Moving on to step 7:
When dividing 8 by 16, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 398630.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 16

On to step 8:
16 can be fit into 85 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3986305.0
Deduct 80 from 85 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.

Step 9:
The number 16 fits into 50 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3986305.3
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
When dividing 20 by 16, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 3986305.31
Subtracting 16 from 20 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
When dividing 40 by 16, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 3986305.312
Deduct 32 from 40 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3986305.3125
Deduct 80 from 80 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.

Going ahead to step 13:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3986305.3125
Subtracting 0 from 0 leaves us 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 14:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3986305.3125
Subtract 0 from 0 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.

The final outcome is 3986305.3125, with a leftover of 0.0.
