We look at the division of 76887901 by 16 
Let's see how many times 16 fits into 76887901.

On to step 1:
16 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 16

Let's proceed to step 2:
If we divide 76 by 16, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 64 from 76 to get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 16

Let's proceed to step 3:
16 goes into 128 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 48.0
If we subtract 128 from 128, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 16

Advancing to step 4:
16 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 480.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 16

Advancing to step 5:
The number 16 fits into 87 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 4805.0
If we take 80 away from 87, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 16

On to step 6:
The number 16 fits into 79 4 times, leaving a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 48054.0
If we take 64 away from 79, we end up with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 16

Let's proceed to step 7:
150 divided by 16 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 480549.0
Deduct 144 from 150 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 16

Advancing to step 8:
If we divide 61 by 16, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 4805493.0
Subtract 48 from 61 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
130 divided by 16 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 4805493.8
If we subtract 128 from 130, we get 2.
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.
The next digit of our result is 1. 
Result so far: 4805493.81
Subtract 16 from 20 to get 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:
The number 16 fits into 40 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 4805493.812
The remainder is 8 after subtracting 32 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
If we divide 80 by 16, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 4805493.8125
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
16 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4805493.8125
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.

Let's proceed to step 14:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4805493.8125
If we subtract 0 from 0, we 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 result is 4805493.8125 with a remainder of 0.0.
