Let's divide 19901324 by 16
The aim is to understand the frequency of 16 in 19901324.

Going ahead to step 1:
The number 16 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 16

On to step 2:
16 goes into 19 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 16 from 19 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 16

Moving on to step 3:
39 divided by 16 is 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 32 from 39, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 16

On to step 4:
When dividing 70 by 16, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Subtracting 64 from 70 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 16

On to step 5:
61 divided by 16 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 1243.0
If we subtract 48 from 61, we get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 16

Moving on to step 6:
16 can be fit into 133 8 times, resulting in a remainder of 5.
The next digit of our result is 8. 
Result so far: 12438.0
Deduct 128 from 133 and we're left with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 16

On to step 7:
When dividing 52 by 16, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 124383.0
Deduct 48 from 52 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 16

On to step 8:
16 can be fit into 44 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 1243832.0
Subtract 32 from 44 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
16 can be fit into 120 7 times, resulting in a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 1243832.7
If we subtract 112 from 120, we 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.

Let's proceed to step 10:
80 divided by 16 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1243832.75
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.

Advancing to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1243832.75
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.

Let's proceed to step 12:
If we divide 0 by 16, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1243832.75
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.

The quotient of the division is 1243832.75, and the remainder is 0.0.
