581607 divided by 16 
The aim is to understand the frequency of 16 in 581607.

Advancing to step 1:
The number 16 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 16

Step 2:
If we divide 58 by 16, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 48 from 58, we get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 16

On to step 3:
The number 16 fits into 101 6 times, leaving a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Deduct 96 from 101 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 16

Moving on to step 4:
16 goes into 56 3 times with a remainder of 8.
The next digit of our result is 3. 
Result so far: 363.0
If we subtract 48 from 56, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 16

Step 5:
If we divide 80 by 16, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3635.0
Deduct 80 from 80 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 16

Step 6:
The number 16 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 36350.0
If we take 0 away from 7, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
The number 16 fits into 70 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 36350.4
Subtract 64 from 70 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.

Advancing to step 8:
The number 16 fits into 60 3 times, leaving a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 36350.43
The remainder is 12 after subtracting 48 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
120 divided by 16 is 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 36350.437
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.

Moving on to step 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 36350.4375
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.

Let's proceed to step 11:
0 divided by 16 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36350.4375
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.

Moving on to step 12:
16 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 36350.4375
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 36350.4375, and the remainder is 0.0.
