641227 divided by 16 
Our goal is to divide 641227 by 16.

Going ahead to step 1:
If we divide 6 by 16, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 16

On to step 2:
When dividing 64 by 16, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 64 from 64 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 16

Moving on to step 3:
1 divided by 16 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 16

Step 4:
When dividing 12 by 16, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 16

Going ahead to step 5:
When dividing 122 by 16, we get 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 4007.0
Subtracting 112 from 122 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 16

On to step 6:
The number 16 fits into 107 6 times, leaving a remainder of 11.
The next digit of our result is 6. 
Result so far: 40076.0
Subtract 96 from 107 to get 11.
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:
If we divide 110 by 16, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 40076.6
Deduct 96 from 110 and we're left 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.

Let's proceed to step 8:
If we divide 140 by 16, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 40076.68
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.

On to step 9:
120 divided by 16 is 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 40076.687
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.

Advancing to step 10:
80 divided by 16 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 40076.6875
Subtracting 80 from 80 leaves us 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.

Advancing to step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40076.6875
The remainder is 0 after subtracting 0 from 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:
0 divided by 16 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40076.6875
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 final result is 40076.6875 with a remainder of 0.0.
