We divide 621381 by 16
We want to figure out the number of times 621381 can be divided by 16.

Moving on to step 1:
16 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 16

Going ahead to step 2:
16 goes into 62 3 times with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 48 away from 62, we end up with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 16

Advancing to step 3:
16 can be fit into 141 8 times, resulting in a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtracting 128 from 141 leaves us with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 16

Step 4:
If we divide 133 by 16, we get 8 and a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 388.0
Deduct 128 from 133 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 16

Moving on to step 5:
When dividing 58 by 16, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3883.0
The remainder is 10 after subtracting 48 from 58.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 16

Let's proceed to step 6:
101 divided by 16 is 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 38836.0
Deduct 96 from 101 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
When dividing 50 by 16, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 38836.3
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
The number 16 fits into 20 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 38836.31
If we take 16 away from 20, we end up 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.

Moving on to step 9:
16 goes into 40 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 38836.312
If we take 32 away from 40, 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.

On to step 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 38836.3125
If we take 80 away from 80, 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.

On to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 38836.3125
Subtracting 0 from 0 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.

Moving on to step 12:
0 divided by 16 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 38836.3125
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 38836.3125, and the remainder is 0.0.
