870159 divided by 16 
Our goal is to divide 870159 by 16.

Advancing to step 1:
If we divide 8 by 16, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 16

Advancing to step 2:
87 divided by 16 is 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 80 from 87 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 16

Advancing to step 3:
When dividing 70 by 16, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 54.0
If we subtract 64 from 70, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 16

Let's proceed to step 4:
16 goes into 61 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 543.0
Subtract 48 from 61 to get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 16

Moving on to step 5:
If we divide 135 by 16, we get 8 and a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 5438.0
Subtracting 128 from 135 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 16

Let's proceed to step 6:
16 can be fit into 79 4 times, resulting in a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 54384.0
The remainder is 15 after subtracting 64 from 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
When dividing 150 by 16, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 54384.9
If we subtract 144 from 150, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
The number 16 fits into 60 3 times, leaving a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 54384.93
If we take 48 away from 60, we end up with 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 9:
120 divided by 16 is 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 54384.937
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 54384.9375
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.

On to step 11:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 54384.9375
If we take 0 away from 0, 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 12:
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: 54384.9375
If we take 0 away from 0, 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.

After the division, we end up with 54384.9375 and a remainder of 0.0.
