We're dividing 237861 by 16 
The aim is to understand the frequency of 16 in 237861.

On to step 1:
If we divide 2 by 16, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 16

Moving on to step 2:
If we divide 23 by 16, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 16 from 23 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 16

On to step 3:
When dividing 77 by 16, we get 4 with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 64 from 77 leaves us with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 16

Step 4:
16 can be fit into 138 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 148.0
The remainder is 10 after subtracting 128 from 138.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 16

Going ahead to step 5:
If we divide 106 by 16, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 1486.0
Deduct 96 from 106 and we're left with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 16

Let's proceed to step 6:
101 divided by 16 is 6 with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 14866.0
Subtract 96 from 101 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
If we divide 50 by 16, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 14866.3
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 16 fits into 20 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 14866.31
Deduct 16 from 20 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
16 goes into 40 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 14866.312
Subtract 32 from 40 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.

Going ahead to step 10:
When dividing 80 by 16, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 14866.3125
The remainder is 0 after subtracting 80 from 80.
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:
If we divide 0 by 16, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14866.3125
If we subtract 0 from 0, 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.

Moving on to step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14866.3125
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.

In conclusion, the division gives 14866.3125 with a balance of 0.0.
