We divide 663407 by 16
We want to figure out the number of times 663407 can be divided by 16.

On to step 1:
16 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 16

Let's proceed to step 2:
16 can be fit into 66 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 2 after subtracting 64 from 66.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 16

Advancing to step 3:
The number 16 fits into 23 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 41.0
If we take 16 away from 23, we end up with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 16

Let's proceed to step 4:
When dividing 74 by 16, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 414.0
Subtracting 64 from 74 leaves us with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 16

Advancing to step 5:
If we divide 100 by 16, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 4146.0
The remainder is 4 after subtracting 96 from 100.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 16

Advancing to step 6:
16 goes into 47 2 times with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 41462.0
If we take 32 away from 47, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
When dividing 150 by 16, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 41462.9
The remainder is 6 after subtracting 144 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
60 divided by 16 is 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 41462.93
If we subtract 48 from 60, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
16 goes into 120 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 41462.937
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
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: 41462.9375
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.

Let's proceed to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 41462.9375
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.

Let's proceed to step 12:
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: 41462.9375
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.

In conclusion, the division gives 41462.9375 with a balance of 0.0.
