We divide 596423 by 16
The aim is to understand the frequency of 16 in 596423.

Going ahead to step 1:
If we divide 5 by 16, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 16

Step 2:
16 can be fit into 59 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 48 away from 59, we end up with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 16

Advancing to step 3:
The number 16 fits into 116 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Deduct 112 from 116 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 16

Going ahead to step 4:
The number 16 fits into 44 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 372.0
The remainder is 12 after subtracting 32 from 44.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 16

Let's proceed to step 5:
122 divided by 16 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 3727.0
If we take 112 away from 122, we end up with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 16

Advancing to step 6:
16 can be fit into 103 6 times, resulting in a remainder of 7.
The next digit of our result is 6. 
Result so far: 37276.0
Deduct 96 from 103 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 16, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 37276.4
If we take 64 away from 70, we end up 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.

Going ahead to step 8:
The number 16 fits into 60 3 times, leaving a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 37276.43
Deduct 48 from 60 and we're left 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.

On to step 9:
The number 16 fits into 120 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 37276.437
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.

Advancing to step 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 37276.4375
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.

Moving on to step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 37276.4375
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.

Advancing to step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 37276.4375
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.

Our division results in 37276.4375 with a remaining 0.0.
