963421 ÷ 16 
Let's see how many times 16 fits into 963421.

Going ahead to step 1:
9 divided by 16 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 16

Going ahead to step 2:
If we divide 96 by 16, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 96 from 96 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 16

Let's proceed to step 3:
If we divide 3 by 16, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 60.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 16

Going ahead to step 4:
16 goes into 34 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 602.0
Subtracting 32 from 34 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 16

Moving on to step 5:
If we divide 22 by 16, we get 1 and a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 6021.0
If we take 16 away from 22, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 16

Moving on to step 6:
16 can be fit into 61 3 times, resulting in a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 60213.0
If we subtract 48 from 61, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
If we divide 130 by 16, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 60213.8
Deduct 128 from 130 and we're left 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.
Record the quotient 1 as the next digit in the result. 
Result so far: 60213.81
If we subtract 16 from 20, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 16, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 60213.812
If we subtract 32 from 40, 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.

Step 10:
16 can be fit into 80 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 60213.8125
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.

Let's proceed 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: 60213.8125
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.

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: 60213.8125
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.

The final result is 60213.8125 with a remainder of 0.0.
