We're dividing 783898 by 16 
The aim is to understand the frequency of 16 in 783898.

On to step 1:
If we divide 7 by 16, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 16

Going ahead to step 2:
16 can be fit into 78 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 64 from 78 and we're left with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 16

On to step 3:
If we divide 143 by 16, we get 8 and a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Deduct 128 from 143 and we're left with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 16

On to step 4:
16 goes into 158 9 times with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 489.0
The remainder is 14 after subtracting 144 from 158.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 16

Let's proceed to step 5:
The number 16 fits into 149 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 4899.0
If we subtract 144 from 149, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 16

Advancing to step 6:
58 divided by 16 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 48993.0
Subtract 48 from 58 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
16 can be fit into 100 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 48993.6
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 16 fits into 40 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 48993.62
If we take 32 away from 40, we end up 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.

Step 9:
When dividing 80 by 16, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 48993.625
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.

Let's proceed to step 10:
16 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 48993.625
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.

Moving on to 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: 48993.625
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.

The quotient of the division is 48993.625, and the remainder is 0.0.
