We're dividing 351685 by 16 
Our goal is to divide 351685 by 16.

Let's proceed to step 1:
16 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 16

Let's proceed to step 2:
35 divided by 16 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 3 after subtracting 32 from 35.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 16

Going ahead to step 3:
16 can be fit into 31 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 16 from 31 leaves us with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 16

Advancing to step 4:
156 divided by 16 is 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 219.0
Deduct 144 from 156 and we're left with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 16

Moving on to step 5:
16 goes into 128 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 2198.0
Deduct 128 from 128 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 16

Moving on to step 6:
When dividing 5 by 16, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 21980.0
Subtracting 0 from 5 leaves us 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.

Moving on to step 7:
When dividing 50 by 16, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 21980.3
Deduct 48 from 50 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.

Step 8:
The number 16 fits into 20 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 21980.31
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.

Let's proceed to step 9:
The number 16 fits into 40 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 21980.312
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:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 21980.3125
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.

Moving on to step 11:
16 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21980.3125
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.

Step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 21980.3125
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.

Our division results in 21980.3125 with a remaining 0.0.
