869998 ÷ 16 
Our goal is to divide 869998 by 16.

On 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.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 16

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
The remainder is 6 after subtracting 80 from 86.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 16

Advancing to step 3:
If we divide 69 by 16, we get 4 and a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we subtract 64 from 69, we get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 16

Going ahead to step 4:
If we divide 59 by 16, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 543.0
Deduct 48 from 59 and we're left with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 16

Going ahead to step 5:
119 divided by 16 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 5437.0
If we take 112 away from 119, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 16

On to step 6:
16 can be fit into 78 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 54374.0
Subtracting 64 from 78 leaves us 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.

Going ahead to step 7:
16 goes into 140 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 54374.8
Subtracting 128 from 140 leaves us 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 8:
120 divided by 16 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 54374.87
Subtracting 112 from 120 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.

Moving on to step 9:
80 divided by 16 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 54374.875
Subtract 80 from 80 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.

Going ahead to step 10:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 54374.875
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.

Let's proceed 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: 54374.875
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.

The final outcome is 54374.875, with a leftover of 0.0.
