874874 divided by 16 
The aim is to understand the frequency of 16 in 874874.

Let's proceed to step 1:
When dividing 8 by 16, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 16

Let's proceed to step 2:
87 divided by 16 is 5 with a remainder of 7.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 80 from 87 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 16

On to step 3:
When dividing 74 by 16, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 54.0
The remainder is 10 after subtracting 64 from 74.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 16

On to step 4:
16 can be fit into 108 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 546.0
If we subtract 96 from 108, we get 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 16

Advancing to step 5:
The number 16 fits into 127 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 5467.0
The remainder is 15 after subtracting 112 from 127.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 16

On to step 6:
16 goes into 154 9 times with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 54679.0
Deduct 144 from 154 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 16, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 54679.6
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 16 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 54679.62
If we take 32 away from 40, 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.

Step 9:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 54679.625
Deduct 80 from 80 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.

Step 10:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 54679.625
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:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 54679.625
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.

The final outcome is 54679.625, with a leftover of 0.0.
