551566 divided by 16 
The aim is to understand the frequency of 16 in 551566.

Let's proceed to step 1:
16 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 16

Let's proceed to step 2:
55 divided by 16 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 48 from 55 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 16

Advancing to step 3:
71 divided by 16 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtracting 64 from 71 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 16

Let's proceed to step 4:
When dividing 75 by 16, we get 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 344.0
If we take 64 away from 75, we end up with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 16

Going ahead to step 5:
16 goes into 116 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 3447.0
Subtract 112 from 116 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 16

Going ahead to step 6:
46 divided by 16 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 34472.0
Subtracting 32 from 46 leaves us 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.

Moving on to step 7:
The number 16 fits into 140 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 34472.8
Subtract 128 from 140 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 8:
If we divide 120 by 16, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 34472.87
Deduct 112 from 120 and we're left 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:
80 divided by 16 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 34472.875
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 10:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 34472.875
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.

Let's proceed to step 11:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 34472.875
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 34472.875, and the remainder is 0.0.
