We're dividing 377982 by 16 
The aim is to understand the frequency of 16 in 377982.

Step 1:
If we divide 3 by 16, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 16

Going ahead to step 2:
37 divided by 16 is 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 32 from 37 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 16

Advancing to step 3:
16 goes into 57 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 48 from 57, we get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 16

Let's proceed to step 4:
99 divided by 16 is 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 236.0
If we subtract 96 from 99, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 16

Moving on to step 5:
If we divide 38 by 16, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2362.0
Deduct 32 from 38 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 16

Advancing to step 6:
16 goes into 62 3 times with a remainder of 14.
The next digit of our result is 3. 
Result so far: 23623.0
Deduct 48 from 62 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
140 divided by 16 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 23623.8
The remainder is 12 after subtracting 128 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
120 divided by 16 is 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 23623.87
Subtract 112 from 120 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 9:
When dividing 80 by 16, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 23623.875
Deduct 80 from 80 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.

Step 10:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 23623.875
If we subtract 0 from 0, 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.

Advancing to step 11:
0 divided by 16 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23623.875
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.

Our division results in 23623.875 with a remaining 0.0.
