We look at the division of 74485349 by 16 
We're looking to find how many times 16 goes into 74485349.

Let's proceed to step 1:
7 divided by 16 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 16

Advancing to step 2:
If we divide 74 by 16, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 64 from 74, we get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 16

On to step 3:
16 can be fit into 104 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtract 96 from 104 to get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 16

Moving on to step 4:
88 divided by 16 is 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 465.0
The remainder is 8 after subtracting 80 from 88.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 16

On to step 5:
85 divided by 16 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4655.0
If we take 80 away from 85, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 16

Let's proceed to step 6:
If we divide 53 by 16, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 46553.0
If we subtract 48 from 53, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 16

Step 7:
16 can be fit into 54 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 465533.0
The remainder is 6 after subtracting 48 from 54.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 16

Advancing to step 8:
If we divide 69 by 16, we get 4 and a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4655334.0
If we take 64 away from 69, we end up 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.

Moving on to step 9:
16 can be fit into 50 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 4655334.3
Subtract 48 from 50 to 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.

On to step 10:
The number 16 fits into 20 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 4655334.31
Deduct 16 from 20 and we're left 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:
The number 16 fits into 40 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 4655334.312
Subtracting 32 from 40 leaves us 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:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4655334.3125
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.

Moving on to step 13:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4655334.3125
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.

On to step 14:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4655334.3125
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 final result is 4655334.3125 with a remainder of 0.0.
