We divide 389521 by 16
We want to divide 389521 by 16.

Step 1:
If we divide 3 by 16, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 16

Going ahead to step 2:
When dividing 38 by 16, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
If we take 32 away from 38, we end up with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 16

Advancing to step 3:
69 divided by 16 is 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 64 away from 69, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 16

Moving on to step 4:
The number 16 fits into 55 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 243.0
If we take 48 away from 55, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 16

On to step 5:
The number 16 fits into 72 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 2434.0
Deduct 64 from 72 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 16

Step 6:
16 goes into 81 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 24345.0
If we take 80 away from 81, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
If we divide 10 by 16, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 24345.0
If we subtract 0 from 10, we 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.

Going ahead to step 8:
When dividing 100 by 16, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 24345.06
If we take 96 away from 100, 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.

Let's proceed to step 9:
When dividing 40 by 16, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 24345.062
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.

Advancing to step 10:
16 goes into 80 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 24345.0625
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:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 24345.0625
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.

Going ahead to step 12:
16 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 24345.0625
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.

The final outcome is 24345.0625, with a leftover of 0.0.
