561910 divided by 16 
The aim is to understand the frequency of 16 in 561910.

On to step 1:
5 divided by 16 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 16

Advancing to step 2:
The number 16 fits into 56 3 times, leaving a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 8 after subtracting 48 from 56.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 16

Advancing to step 3:
When dividing 81 by 16, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtract 80 from 81 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 16

Advancing to step 4:
19 divided by 16 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 351.0
If we take 16 away from 19, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 16

Advancing to step 5:
When dividing 31 by 16, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 3511.0
Deduct 16 from 31 and we're left with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 16

Let's proceed to step 6:
The number 16 fits into 150 9 times, leaving a remainder of 6.
The next digit of our result is 9. 
Result so far: 35119.0
Subtract 144 from 150 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 16 is 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 35119.3
If we take 48 away from 60, 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.

On to step 8:
When dividing 120 by 16, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 35119.37
Subtracting 112 from 120 leaves us 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.

Let's proceed to step 9:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 35119.375
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:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 35119.375
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.

Advancing 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: 35119.375
Subtract 0 from 0 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.

In conclusion, the division gives 35119.375 with a balance of 0.0.
