67915319 divided by 16 
The aim is to understand the frequency of 16 in 67915319.

On to step 1:
16 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 16

Going ahead to step 2:
16 goes into 67 4 times with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 64 from 67 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 16

Moving on to step 3:
16 can be fit into 39 2 times, resulting in a remainder of 7.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 32 from 39 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 16

Moving on to step 4:
16 can be fit into 71 4 times, resulting in a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 424.0
Deduct 64 from 71 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 16

On to step 5:
When dividing 75 by 16, we get 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 4244.0
If we take 64 away from 75, we end up with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 16

Advancing to step 6:
113 divided by 16 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 42447.0
If we take 112 away from 113, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 16

Step 7:
The number 16 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 424470.0
If we take 0 away from 11, we end up with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 16

Advancing to step 8:
The number 16 fits into 119 7 times, leaving a remainder of 7.
The next digit of our result is 7. 
Result so far: 4244707.0
The remainder is 7 after subtracting 112 from 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
70 divided by 16 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4244707.4
Subtract 64 from 70 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
If we divide 60 by 16, we get 3 and a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 4244707.43
If we take 48 away from 60, we end up 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.

Going ahead to step 11:
16 goes into 120 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 4244707.437
Subtract 112 from 120 to 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 12:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4244707.4375
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.

Going ahead to step 13:
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: 4244707.4375
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 14:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4244707.4375
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.

After the division, we end up with 4244707.4375 and a remainder of 0.0.
