398299 ÷ 16 
The aim is to understand the frequency of 16 in 398299.

On to step 1:
If we divide 3 by 16, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 16

Advancing to step 2:
If we divide 39 by 16, we get 2 and a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 32 from 39 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 16

On to step 3:
When dividing 78 by 16, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 64 away from 78, we end up with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 16

Let's proceed to step 4:
16 goes into 142 8 times with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 248.0
Subtract 128 from 142 to get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 16

Advancing to step 5:
16 can be fit into 149 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 2489.0
If we subtract 144 from 149, we get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 16

Moving on to step 6:
When dividing 59 by 16, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 24893.0
Subtract 48 from 59 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.
Put 6 as the next digit of the answer. 
Result so far: 24893.6
If we take 96 away from 110, we end up 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 8:
If we divide 140 by 16, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 24893.68
The remainder is 12 after subtracting 128 from 140.
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.
The next digit of our result is 7. 
Result so far: 24893.687
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.

Moving on to step 10:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 24893.6875
Deduct 80 from 80 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.

Advancing to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 24893.6875
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.

Going ahead to step 12:
16 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24893.6875
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 final result is 24893.6875 with a remainder of 0.0.
