We're dividing 771620 by 16 
The aim is to understand the frequency of 16 in 771620.

Moving on to step 1:
When dividing 7 by 16, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 16

Let's proceed to step 2:
When dividing 77 by 16, we get 4 with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 64 from 77 and we're left with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 16

Let's proceed to step 3:
When dividing 131 by 16, we get 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 128 from 131 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 16

Let's proceed to step 4:
The number 16 fits into 36 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 482.0
Deduct 32 from 36 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 16

Step 5:
42 divided by 16 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 4822.0
If we take 32 away from 42, we end up with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 16

Moving on to step 6:
16 goes into 100 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 48226.0
The remainder is 4 after subtracting 96 from 100.
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 7:
16 can be fit into 40 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 48226.2
Subtract 32 from 40 to 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 8:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 48226.25
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.

Going ahead to step 9:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 48226.25
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.

Step 10:
16 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48226.25
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 48226.25 with a balance of 0.0.
