We look at the division of 863170 by 16 
We want to figure out the number of times 863170 can be divided by 16.

Step 1:
8 divided by 16 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 16

Moving on to step 2:
The number 16 fits into 86 5 times, leaving a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 80 away from 86, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 16

Going ahead to step 3:
16 can be fit into 63 3 times, resulting in a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtracting 48 from 63 leaves us with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 16

Moving on to step 4:
If we divide 151 by 16, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 539.0
The remainder is 7 after subtracting 144 from 151.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 16

On to step 5:
16 goes into 77 4 times with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 5394.0
If we take 64 away from 77, we end up with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 16

Moving on to step 6:
If we divide 130 by 16, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 53948.0
Deduct 128 from 130 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.

On to step 7:
20 divided by 16 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 53948.1
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.

Step 8:
When dividing 40 by 16, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 53948.12
Subtracting 32 from 40 leaves us 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.

Let's proceed to step 9:
When dividing 80 by 16, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 53948.125
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.

Step 10:
16 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 53948.125
Subtracting 0 from 0 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.

Moving on to step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 53948.125
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.

After the division, we end up with 53948.125 and a remainder of 0.0.
