We divide 312431 by 16
The aim is to understand the frequency of 16 in 312431.

Step 1:
16 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 16

Advancing to step 2:
When dividing 31 by 16, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 16 from 31, we get 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 16

Step 3:
16 goes into 152 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 144 from 152 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 16

Moving on to step 4:
The number 16 fits into 84 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 195.0
Subtracting 80 from 84 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 16

Going ahead to step 5:
The number 16 fits into 43 2 times, leaving a remainder of 11.
The next digit of our result is 2. 
Result so far: 1952.0
If we subtract 32 from 43, we get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 16

Moving on to step 6:
When dividing 111 by 16, we get 6 with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 19526.0
The remainder is 15 after subtracting 96 from 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
16 can be fit into 150 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 19526.9
Deduct 144 from 150 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
60 divided by 16 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 19526.93
The remainder is 12 after subtracting 48 from 60.
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 9:
120 divided by 16 is 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 19526.937
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 16, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 19526.9375
Subtract 80 from 80 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.

Let's proceed to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19526.9375
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.

On to step 12:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19526.9375
If we take 0 away from 0, 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.

The final outcome is 19526.9375, with a leftover of 0.0.
