We're dividing 774458 by 16 
We want to divide 774458 by 16.

Advancing to step 1:
16 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 16

Moving on to step 2:
If we divide 77 by 16, we get 4 and a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 64 from 77, we get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 16

Advancing to step 3:
16 can be fit into 134 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we take 128 away from 134, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 16

On to step 4:
16 can be fit into 64 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 484.0
If we subtract 64 from 64, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 16

Step 5:
5 divided by 16 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 4840.0
Subtract 0 from 5 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 16

Advancing to step 6:
The number 16 fits into 58 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 48403.0
Subtracting 48 from 58 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 16 fits into 100 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 48403.6
Subtract 96 from 100 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.

Advancing to step 8:
40 divided by 16 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 48403.62
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 9:
When dividing 80 by 16, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 48403.625
If we subtract 80 from 80, 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.

Advancing to step 10:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 48403.625
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.

Let's proceed to step 11:
16 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 48403.625
Deduct 0 from 0 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.

The quotient of the division is 48403.625, and the remainder is 0.0.
