We look at the division of 610851 by 16 
The aim is to understand the frequency of 16 in 610851.

Step 1:
The number 16 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 16

Moving on to step 2:
If we divide 61 by 16, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 48 away from 61, we end up with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 16

Moving on to step 3:
16 can be fit into 130 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
The remainder is 2 after subtracting 128 from 130.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 16

Advancing to step 4:
When dividing 28 by 16, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 381.0
Deduct 16 from 28 and we're left with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 16

On to step 5:
When dividing 125 by 16, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 3817.0
The remainder is 13 after subtracting 112 from 125.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 16

Advancing to step 6:
16 can be fit into 131 8 times, resulting in a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 38178.0
Subtract 128 from 131 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
30 divided by 16 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 38178.1
Subtract 16 from 30 to get 14.
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 8:
When dividing 140 by 16, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 38178.18
If we take 128 away from 140, we end up 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.

Advancing to step 9:
16 can be fit into 120 7 times, resulting in a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 38178.187
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.

On 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: 38178.1875
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.

Step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 38178.1875
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.

Let's proceed to step 12:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 38178.1875
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.

The final outcome is 38178.1875, with a leftover of 0.0.
