We're dividing 854166 by 16 
The aim is to understand the frequency of 16 in 854166.

Moving on to step 1:
The number 16 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 16

On to step 2:
The number 16 fits into 85 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 80 from 85 and we're left with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 16

Going ahead to step 3:
16 goes into 54 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 53.0
The remainder is 6 after subtracting 48 from 54.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 16

Going ahead to step 4:
16 goes into 61 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 533.0
Subtract 48 from 61 to get 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 16

Going ahead to step 5:
136 divided by 16 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 5338.0
Deduct 128 from 136 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 16

Going ahead to step 6:
If we divide 86 by 16, we get 5 and a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 53385.0
Subtracting 80 from 86 leaves us 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.

Advancing to step 7:
16 goes into 60 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 53385.3
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.

Going ahead to step 8:
The number 16 fits into 120 7 times, leaving a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 53385.37
If we take 112 away from 120, we end up with 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 9:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 53385.375
If we take 80 away from 80, 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.

On to step 10:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 53385.375
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.

Moving on to 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: 53385.375
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 outcome is 53385.375, with a leftover of 0.0.
