We divide 401687 by 16
We want to figure out the number of times 401687 can be divided by 16.

Let's proceed to step 1:
16 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 16

Step 2:
16 goes into 40 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 32 from 40 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 16

On to step 3:
81 divided by 16 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 1 after subtracting 80 from 81.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 16

Going ahead to step 4:
16 goes into 16 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 251.0
If we take 16 away from 16, we end up with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 16

Going ahead to step 5:
16 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 2510.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 16

Advancing to step 6:
If we divide 87 by 16, we get 5 and a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 25105.0
Deduct 80 from 87 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
16 can be fit into 70 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 25105.4
If we subtract 64 from 70, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
60 divided by 16 is 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 25105.43
The remainder is 12 after subtracting 48 from 60.
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: 25105.437
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead 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: 25105.4375
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.

Going ahead to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25105.4375
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.

On to step 12:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 25105.4375
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.

Our division results in 25105.4375 with a remaining 0.0.
