64739565 divided by 16 
We're looking to find how many times 16 goes into 64739565.

Moving on to step 1:
16 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 16

Step 2:
16 can be fit into 64 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 64 from 64 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 16

Moving on to step 3:
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: 40.0
If we subtract 0 from 7, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 16

Step 4:
When dividing 73 by 16, we get 4 with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 404.0
Deduct 64 from 73 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 16

Going ahead to step 5:
The number 16 fits into 99 6 times, leaving a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 4046.0
Subtracting 96 from 99 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 16

Step 6:
35 divided by 16 is 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 40462.0
If we subtract 32 from 35, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 16

Let's proceed to step 7:
16 goes into 36 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 404622.0
Subtracting 32 from 36 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 16

Step 8:
If we divide 45 by 16, we get 2 and a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 4046222.0
Subtracting 32 from 45 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
The number 16 fits into 130 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 4046222.8
Subtract 128 from 130 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.

Advancing to step 10:
20 divided by 16 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 4046222.81
Subtracting 16 from 20 leaves us 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.

Advancing to step 11:
16 can be fit into 40 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 4046222.812
Deduct 32 from 40 and we're left 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.

Let's proceed to step 12:
If we divide 80 by 16, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4046222.8125
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.

On to step 13:
If we divide 0 by 16, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 4046222.8125
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.

Advancing to step 14:
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: 4046222.8125
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.

Our division results in 4046222.8125 with a remaining 0.0.
