340845 divided by 16 
Let's see how many times 16 fits into 340845.

Step 1:
The number 16 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 16

On to step 2:
34 divided by 16 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 32 from 34 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 16

Let's proceed to step 3:
16 goes into 20 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 16 from 20 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 16

On to step 4:
The number 16 fits into 48 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 213.0
Subtracting 48 from 48 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 16

Advancing to step 5:
If we divide 4 by 16, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 2130.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 16

Step 6:
16 goes into 45 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 21302.0
If we subtract 32 from 45, 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.

Going ahead to step 7:
When dividing 130 by 16, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 21302.8
If we subtract 128 from 130, we get 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:
16 goes into 20 1 times with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 21302.81
Subtracting 16 from 20 leaves us 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.

Going ahead to step 9:
16 can be fit into 40 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 21302.812
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.

Going ahead to step 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 21302.8125
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.

Step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21302.8125
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.

Advancing to step 12:
If we divide 0 by 16, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21302.8125
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.

After the division, we end up with 21302.8125 and a remainder of 0.0.
