We look at the division of 764451 by 16 
We want to divide 764451 by 16.

Step 1:
The number 16 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 16

Step 2:
If we divide 76 by 16, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 64 from 76 and we're left with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 16

On to step 3:
124 divided by 16 is 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we take 112 away from 124, we end up with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 16

Going ahead to step 4:
When dividing 124 by 16, we get 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 477.0
If we subtract 112 from 124, we get 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 16

Step 5:
The number 16 fits into 125 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 4777.0
The remainder is 13 after subtracting 112 from 125.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 16

Advancing to step 6:
The number 16 fits into 131 8 times, leaving a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 47778.0
Subtract 128 from 131 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
16 goes into 30 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 47778.1
Subtract 16 from 30 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
16 goes into 140 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 47778.18
The remainder is 12 after subtracting 128 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
120 divided by 16 is 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 47778.187
The remainder is 8 after subtracting 112 from 120.
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 10:
16 goes into 80 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 47778.1875
Subtracting 80 from 80 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.

Step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 47778.1875
If we take 0 away from 0, we end up 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.

Moving on to step 12:
16 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 47778.1875
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 quotient of the division is 47778.1875, and the remainder is 0.0.
