751803 ÷ 16 
The aim is to understand the frequency of 16 in 751803.

Step 1:
16 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 16

On to step 2:
If we divide 75 by 16, we get 4 and a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
If we take 64 away from 75, we end up with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 16

Moving on to step 3:
When dividing 111 by 16, we get 6 with a remainder of 15.
The next digit of our result is 6. 
Result so far: 46.0
Subtracting 96 from 111 leaves us with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 16

Step 4:
16 goes into 158 9 times with a remainder of 14.
The next digit of our result is 9. 
Result so far: 469.0
The remainder is 14 after subtracting 144 from 158.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 16

Step 5:
When dividing 140 by 16, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 4698.0
If we take 128 away from 140, we end up with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 16

Step 6:
If we divide 123 by 16, we get 7 and a remainder of 11.
The next digit of our result is 7. 
Result so far: 46987.0
Subtract 112 from 123 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 16 fits into 110 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 46987.6
Subtracting 96 from 110 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.

Let's proceed to step 8:
When dividing 140 by 16, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 46987.68
Deduct 128 from 140 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
16 can be fit into 120 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 46987.687
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.

Step 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 46987.6875
If we subtract 80 from 80, 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.

On to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 46987.6875
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.

On to step 12:
16 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 46987.6875
Subtract 0 from 0 to 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.

The quotient of the division is 46987.6875, and the remainder is 0.0.
