642475 ÷ 16 
We're looking to find how many times 16 goes into 642475.

Going ahead to step 1:
16 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 16

Let's proceed to step 2:
16 can be fit into 64 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 0 after subtracting 64 from 64.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 16

Step 3:
16 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 40.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 16

Moving on to step 4:
24 divided by 16 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 401.0
Subtract 16 from 24 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 16

Moving on to step 5:
If we divide 87 by 16, we get 5 and a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 4015.0
The remainder is 7 after subtracting 80 from 87.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 16

Let's proceed to step 6:
75 divided by 16 is 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 40154.0
If we take 64 away from 75, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
110 divided by 16 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 40154.6
If we take 96 away from 110, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
When dividing 140 by 16, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 40154.68
If we take 128 away from 140, 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.

Going ahead to step 9:
16 goes into 120 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 40154.687
If we subtract 112 from 120, we get 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 10:
16 goes into 80 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 40154.6875
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.

Moving on to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40154.6875
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.

Let's proceed to step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40154.6875
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.

In conclusion, the division gives 40154.6875 with a balance of 0.0.
