We divide 399160 by 16
The aim is to understand the frequency of 16 in 399160.

On to step 1:
3 divided by 16 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 16

Let's proceed to step 2:
16 can be fit into 39 2 times, resulting in a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 32 away from 39, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 16

On to step 3:
16 goes into 79 4 times with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 64 from 79, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 16

Advancing to step 4:
When dividing 151 by 16, we get 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 249.0
Deduct 144 from 151 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 16

Going ahead to step 5:
16 can be fit into 76 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 2494.0
Subtract 64 from 76 to get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 16

Step 6:
The number 16 fits into 120 7 times, leaving a remainder of 8.
The next digit of our result is 7. 
Result so far: 24947.0
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 7:
When dividing 80 by 16, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 24947.5
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.

Going ahead to step 8:
0 divided by 16 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 24947.5
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.

Going ahead to step 9:
When dividing 0 by 16, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 24947.5
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.

After the division, we end up with 24947.5 and a remainder of 0.0.
