Let's divide 74580 by 16
The aim is to understand the frequency of 16 in 74580.

On to step 1:
The number 16 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 16

Step 2:
The number 16 fits into 74 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 64 from 74 and we're left with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 16

Let's proceed to step 3:
16 can be fit into 105 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we take 96 away from 105, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 16

Advancing to step 4:
98 divided by 16 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 466.0
Subtracting 96 from 98 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 16

Advancing to step 5:
When dividing 20 by 16, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 4661.0
The remainder is 4 after subtracting 16 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 6:
40 divided by 16 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 4661.2
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.

Moving on to step 7:
If we divide 80 by 16, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4661.25
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 8:
16 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4661.25
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.

Advancing to step 9:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4661.25
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 final outcome is 4661.25, with a leftover of 0.0.
