217594 divided by 16 
The aim is to understand the frequency of 16 in 217594.

Going ahead to step 1:
16 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 16

On to step 2:
If we divide 21 by 16, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 16 from 21 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 16

On to step 3:
16 goes into 57 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 48 from 57 leaves us with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 16

Let's proceed to step 4:
When dividing 95 by 16, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
Subtracting 80 from 95 leaves us with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 16

Going ahead to step 5:
The number 16 fits into 159 9 times, leaving a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 1359.0
Subtracting 144 from 159 leaves us with 15.
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.
Use 9 as the next digit of our solution. 
Result so far: 13599.0
If we subtract 144 from 154, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
16 goes into 100 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 13599.6
Subtracting 96 from 100 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
If we divide 40 by 16, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 13599.62
The remainder is 8 after subtracting 32 from 40.
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:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 13599.625
If we subtract 80 from 80, 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.

On to step 10:
0 divided by 16 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13599.625
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.

On to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13599.625
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.

The quotient of the division is 13599.625, and the remainder is 0.0.
