189641 divided by 16 
The aim is to understand the frequency of 16 in 189641.

On to step 1:
The number 16 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 16

On to step 2:
16 can be fit into 18 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 2 after subtracting 16 from 18.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 16

Going ahead to step 3:
16 can be fit into 29 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 16 away from 29, we end up with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 16

On to step 4:
When dividing 136 by 16, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 118.0
If we take 128 away from 136, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 16

Moving on to step 5:
The number 16 fits into 84 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 1185.0
If we subtract 80 from 84, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 16

Let's proceed to step 6:
When dividing 41 by 16, we get 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 11852.0
Deduct 32 from 41 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
The number 16 fits into 90 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 11852.5
If we take 80 away from 90, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
16 goes into 100 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 11852.56
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 9:
When dividing 40 by 16, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 11852.562
Subtracting 32 from 40 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.

Let's proceed to step 10:
16 goes into 80 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11852.5625
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.

Step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11852.5625
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.

Let's proceed to step 12:
If we divide 0 by 16, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11852.5625
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.

Our division results in 11852.5625 with a remaining 0.0.
