We look at the division of 977141 by 16 
The aim is to understand the frequency of 16 in 977141.

Let's proceed to step 1:
If we divide 9 by 16, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 16

Step 2:
97 divided by 16 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 96 from 97 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 16

Step 3:
17 divided by 16 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we subtract 16 from 17, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 16

Advancing to step 4:
16 goes into 11 0 times with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 610.0
The remainder is 11 after subtracting 0 from 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 16

Advancing to step 5:
16 goes into 114 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 6107.0
Subtract 112 from 114 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 16

Going ahead to step 6:
16 can be fit into 21 1 times, resulting in a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 61071.0
The remainder is 5 after subtracting 16 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
50 divided by 16 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 61071.3
Subtracting 48 from 50 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
If we divide 20 by 16, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 61071.31
If we subtract 16 from 20, 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.

Let's proceed to step 9:
40 divided by 16 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 61071.312
Deduct 32 from 40 and we're left 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.

Moving on to step 10:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 61071.3125
The remainder is 0 after subtracting 80 from 80.
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 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: 61071.3125
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.

Going ahead to step 12:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 61071.3125
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 61071.3125 with a remainder of 0.0.
