We're dividing 39942401 by 16 
We want to divide 39942401 by 16.

Let's proceed to step 1:
16 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 16

Step 2:
The number 16 fits into 39 2 times, leaving a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 32 from 39 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 16

Let's proceed to step 3:
If we divide 79 by 16, we get 4 and a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 64 from 79 and we're left with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 16

Let's proceed to step 4:
154 divided by 16 is 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 249.0
Subtract 144 from 154 to get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 16

Moving on to step 5:
16 can be fit into 102 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 2496.0
Subtract 96 from 102 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 16

Advancing to step 6:
64 divided by 16 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 24964.0
Deduct 64 from 64 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 16

Advancing to step 7:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 249640.0
If we subtract 0 from 0, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 16

Let's proceed to step 8:
16 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 2496400.0
If we take 0 away from 1, 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 9:
When dividing 10 by 16, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2496400.0
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.

Moving on to step 10:
100 divided by 16 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 2496400.06
If we subtract 96 from 100, 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.

Step 11:
40 divided by 16 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2496400.062
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 12:
16 goes into 80 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2496400.0625
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.

Step 13:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2496400.0625
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 14:
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: 2496400.0625
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.

After the division, we end up with 2496400.0625 and a remainder of 0.0.
