We're dividing 742488 by 16 
We want to figure out the number of times 742488 can be divided by 16.

Going ahead to step 1:
16 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 16

Let's proceed to step 2:
16 goes into 74 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 64 from 74 to get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 16

Advancing to step 3:
The number 16 fits into 102 6 times, leaving a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Subtract 96 from 102 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 16

Step 4:
The number 16 fits into 64 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 464.0
The remainder is 0 after subtracting 64 from 64.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 16

Step 5:
8 divided by 16 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 4640.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 16

Step 6:
16 can be fit into 88 5 times, resulting in a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 46405.0
The remainder is 8 after subtracting 80 from 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 46405.5
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.

On to step 8:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 46405.5
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 9:
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: 46405.5
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.

The final result is 46405.5 with a remainder of 0.0.
