We look at the division of 142636 by 8 
Let's see how many times 8 fits into 142636.

Moving on to step 1:
If we divide 1 by 8, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 8

On to step 2:
8 can be fit into 14 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 8 from 14 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 8

Advancing to step 3:
62 divided by 8 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 17.0
If we take 56 away from 62, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 8

Let's proceed to step 4:
If we divide 66 by 8, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 178.0
If we take 64 away from 66, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 8

Advancing to step 5:
23 divided by 8 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 1782.0
Subtracting 16 from 23 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 8

Going ahead to step 6:
The number 8 fits into 76 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 17829.0
Subtracting 72 from 76 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.

Let's proceed to step 7:
8 goes into 40 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 17829.5
Subtract 40 from 40 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.

Advancing to step 8:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17829.5
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.

Going ahead to step 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17829.5
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 17829.5, with a leftover of 0.0.
