631345 divided by 16 
The aim is to understand the frequency of 16 in 631345.

Advancing to step 1:
16 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 16

Moving on to step 2:
The number 16 fits into 63 3 times, leaving a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 15 after subtracting 48 from 63.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 16

Step 3:
151 divided by 16 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtract 144 from 151 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 16

Step 4:
The number 16 fits into 73 4 times, leaving a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 394.0
If we subtract 64 from 73, we get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 16

Step 5:
The number 16 fits into 94 5 times, leaving a remainder of 14.
The next digit of our result is 5. 
Result so far: 3945.0
Subtracting 80 from 94 leaves us with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 16

Step 6:
145 divided by 16 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 39459.0
Subtract 144 from 145 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
If we divide 10 by 16, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 39459.0
Subtract 0 from 10 to 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 8:
16 can be fit into 100 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 39459.06
Deduct 96 from 100 and we're left 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.

Advancing to step 9:
If we divide 40 by 16, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 39459.062
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.

Step 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 39459.0625
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.

Let's proceed to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39459.0625
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.

Advancing to step 12:
If we divide 0 by 16, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39459.0625
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.

The quotient of the division is 39459.0625, and the remainder is 0.0.
