We divide 664175 by 16
The aim is to understand the frequency of 16 in 664175.

Going ahead to step 1:
When dividing 6 by 16, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 16

Going ahead to step 2:
16 goes into 66 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 64 from 66 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 16

On to step 3:
The number 16 fits into 24 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 41.0
Deduct 16 from 24 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 16

Step 4:
The number 16 fits into 81 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 415.0
Subtract 80 from 81 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 16

Advancing to step 5:
The number 16 fits into 17 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 4151.0
Deduct 16 from 17 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 16

Going ahead to step 6:
16 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 41510.0
Subtracting 0 from 15 leaves us 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:
16 goes into 150 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 41510.9
Subtract 144 from 150 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
16 can be fit into 60 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 41510.93
If we take 48 away from 60, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
120 divided by 16 is 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 41510.937
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 41510.9375
If we take 80 away from 80, 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.

Advancing to step 11:
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: 41510.9375
The remainder is 0 after subtracting 0 from 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:
0 divided by 16 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41510.9375
The remainder is 0 after subtracting 0 from 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 41510.9375 with a remainder of 0.0.
