142872 ÷ 8 
We want to figure out the number of times 142872 can be divided by 8.

Advancing to step 1:
When dividing 1 by 8, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 8

On to step 2:
If we divide 14 by 8, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 8 away from 14, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 8

Advancing to step 3:
If we divide 62 by 8, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 6 after subtracting 56 from 62.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 8

Moving on to step 4:
When dividing 68 by 8, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 178.0
The remainder is 4 after subtracting 64 from 68.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 8

Going ahead to step 5:
8 goes into 47 5 times with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 1785.0
Deduct 40 from 47 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 8

Moving on to step 6:
72 divided by 8 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 17859.0
Deduct 72 from 72 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.

Going ahead to step 7:
8 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: 17859.0
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.

Let's proceed to step 8:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17859.0
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.

The quotient of the division is 17859.0, and the remainder is 0.0.
