We divide 863438 by 16
Let's see how many times 16 fits into 863438.

Moving on to step 1:
16 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 16

Going ahead to step 2:
86 divided by 16 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 80 from 86, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 16

Going ahead to step 3:
When dividing 63 by 16, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 53.0
Deduct 48 from 63 and we're left with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 16

On to step 4:
The number 16 fits into 154 9 times, leaving a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 539.0
Deduct 144 from 154 and we're left with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 16

Going ahead to step 5:
16 goes into 103 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 5396.0
The remainder is 7 after subtracting 96 from 103.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 16

Going ahead to step 6:
When dividing 78 by 16, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 53964.0
Deduct 64 from 78 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
140 divided by 16 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 53964.8
If we subtract 128 from 140, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
When dividing 120 by 16, we get 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 53964.87
Deduct 112 from 120 and we're left 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.

Moving on to step 9:
16 goes into 80 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 53964.875
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 53964.875
The remainder is 0 after subtracting 0 from 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 11:
16 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 53964.875
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.

The final outcome is 53964.875, with a leftover of 0.0.
