We divide 642315 by 16
We want to divide 642315 by 16.

Step 1:
If we divide 6 by 16, we get 0 and 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.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 16

Moving on to step 2:
64 divided by 16 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 64 from 64 to get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 16

Step 3:
If we divide 2 by 16, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 16

Advancing to step 4:
23 divided by 16 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 401.0
If we subtract 16 from 23, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 16

Let's proceed to step 5:
When dividing 71 by 16, we get 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4014.0
Deduct 64 from 71 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 16

Moving on to step 6:
The number 16 fits into 75 4 times, leaving a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 40144.0
The remainder is 11 after subtracting 64 from 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
16 goes into 110 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 40144.6
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.

On to step 8:
If we divide 140 by 16, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 40144.68
Subtract 128 from 140 to get 12.
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:
16 goes into 120 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 40144.687
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to 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: 40144.6875
Subtract 80 from 80 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 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: 40144.6875
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.

Going ahead to step 12:
0 divided by 16 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40144.6875
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.

The quotient of the division is 40144.6875, and the remainder is 0.0.
