778651 ÷ 16 
The aim is to understand the frequency of 16 in 778651.

Moving on to step 1:
The number 16 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 16

Let's proceed to step 2:
If we divide 77 by 16, we get 4 and a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 64 from 77 leaves us with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 16

Step 3:
If we divide 138 by 16, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 48.0
The remainder is 10 after subtracting 128 from 138.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 16

Step 4:
16 can be fit into 106 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 486.0
If we take 96 away from 106, we end up with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 16

Step 5:
16 goes into 105 6 times with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 4866.0
Subtracting 96 from 105 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 16

Step 6:
If we divide 91 by 16, we get 5 and a remainder of 11.
The next digit of our result is 5. 
Result so far: 48665.0
Subtract 80 from 91 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
If we divide 110 by 16, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 48665.6
Subtract 96 from 110 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
140 divided by 16 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 48665.68
Subtracting 128 from 140 leaves us 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.
Use 7 as the next digit of our solution. 
Result so far: 48665.687
Subtracting 112 from 120 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 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 48665.6875
Subtracting 80 from 80 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.

Step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 48665.6875
Subtract 0 from 0 to 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 12:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 48665.6875
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.

The final result is 48665.6875 with a remainder of 0.0.
