We're dividing 25634995 by 16 
The aim is to understand the frequency of 16 in 25634995.

On to step 1:
2 divided by 16 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 16

Advancing to step 2:
25 divided by 16 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 16 away from 25, we end up with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 16

Let's proceed to step 3:
96 divided by 16 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 96 from 96 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 16

Advancing to step 4:
When dividing 3 by 16, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 16

Let's proceed to step 5:
16 can be fit into 34 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 1602.0
If we subtract 32 from 34, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 16

Advancing to step 6:
16 goes into 29 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 16021.0
If we take 16 away from 29, we end up with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 16

Moving on to step 7:
The number 16 fits into 139 8 times, leaving a remainder of 11.
The next digit of our result is 8. 
Result so far: 160218.0
If we subtract 128 from 139, we get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 16

On to step 8:
115 divided by 16 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1602187.0
Subtracting 112 from 115 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
When dividing 30 by 16, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1602187.1
The remainder is 14 after subtracting 16 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
140 divided by 16 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 1602187.18
If we subtract 128 from 140, we get 12.
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 11:
16 goes into 120 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 1602187.187
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.

On to step 12:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1602187.1875
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.

On to step 13:
0 divided by 16 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1602187.1875
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.

Moving on to step 14:
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: 1602187.1875
Deduct 0 from 0 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.

After the division, we end up with 1602187.1875 and a remainder of 0.0.
