139867 ÷ 8 
Our goal is to divide 139867 by 8.

Advancing to step 1:
1 divided by 8 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 8

Going ahead to step 2:
8 can be fit into 13 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 8 away from 13, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 8

Advancing to step 3:
8 goes into 59 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 56 from 59, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 8

Moving on to step 4:
The number 8 fits into 38 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 174.0
The remainder is 6 after subtracting 32 from 38.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 8

Going ahead to step 5:
66 divided by 8 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 1748.0
Subtracting 64 from 66 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 8

Step 6:
The number 8 fits into 27 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 17483.0
Deduct 24 from 27 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
30 divided by 8 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 17483.3
Deduct 24 from 30 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
60 divided by 8 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 17483.37
Subtracting 56 from 60 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.

Going ahead to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 17483.375
Deduct 40 from 40 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.

On to step 10:
0 divided by 8 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17483.375
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.

Going ahead to step 11:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17483.375
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.

After the division, we end up with 17483.375 and a remainder of 0.0.
