We're dividing 66653828 by 16 
We want to figure out the number of times 66653828 can be divided by 16.

Moving on to step 1:
16 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 16

Moving on to step 2:
16 can be fit into 66 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 64 from 66, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 16

Advancing to step 3:
When dividing 26 by 16, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we take 16 away from 26, we end up with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 16

Advancing to step 4:
105 divided by 16 is 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 416.0
If we take 96 away from 105, we end up with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 16

Step 5:
16 can be fit into 93 5 times, resulting in a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 4165.0
If we subtract 80 from 93, we get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 16

Going ahead to step 6:
The number 16 fits into 138 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 41658.0
Deduct 128 from 138 and we're left with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 16

Moving on to step 7:
102 divided by 16 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 416586.0
Deduct 96 from 102 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 16

Step 8:
When dividing 68 by 16, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4165864.0
If we subtract 64 from 68, we 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.

On to step 9:
16 goes into 40 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 4165864.2
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.

Moving on to step 10:
16 goes into 80 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4165864.25
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.

Step 11:
16 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4165864.25
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.

Step 12:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4165864.25
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.

Our division results in 4165864.25 with a remaining 0.0.
