We're dividing 813888 by 16 
We want to figure out the number of times 813888 can be divided by 16.

Going ahead to step 1:
16 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 16

Let's proceed to step 2:
81 divided by 16 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 1 after subtracting 80 from 81.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 16

Moving on to step 3:
16 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we subtract 0 from 13, we get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 16

Step 4:
If we divide 138 by 16, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 508.0
Subtract 128 from 138 to get 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 16

Step 5:
If we divide 108 by 16, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 5086.0
If we take 96 away from 108, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 16

Going ahead to step 6:
16 can be fit into 128 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 50868.0
Subtracting 128 from 128 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.

Advancing to step 7:
16 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50868.0
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.

Advancing to step 8:
When dividing 0 by 16, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50868.0
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 50868.0 with a remainder of 0.0.
